  https://www.ncbi.nlm.nih.gov/sites/books/NBK430938/

  Nipple discharge is the third most common breast complaint after breast pain and breast mass. Fifty percent to 80% of women in their reproductive years have nipple discharge, and 6.8% of these are referred to a breast surgeon. Most nipple discharge is benign in origin (97%). […] The clinical history is most helpful in distinguishing benign from suspicious or pathologic nipple discharge. The patient’s age is very important, as women greater than 40 years of age are at higher risk of having pathologic discharge. Postmenopausal women with nipple discharge are rarely benign. […] The primary goal of evaluation of the nipple discharge in a general outpatient setting or the emergency department is to distinguish patients with benign discharge from those with underlying breast cancer, infection/abscess, or those patients who are at high risk of developing pathologic processes.

  Nipple discharge is the third most common breast-related complaint, after breast pain and breast mass. During their reproductive years, up to 80 percent of women will have an episode of nipple discharge. […] Most nipple discharge is of benign origin. The primary goals of evaluation and management are to differentiate patients with benign nipple discharge from those who have an underlying papilloma, high-risk lesion, or malignancy and to manage patients with underlying pathologic nipple discharge. […] The types of nipple discharge and how to evaluate and manage this common problem will be reviewed here. The surgical management of pathologic nipple discharge is discussed in a separate topic. […] Nipple discharge is categorized as normal milk production (lactation), physiologic nipple discharge (galactorrhea), or pathologic (suspicious) nipple discharge based on the characteristics of presentation.

  Nipple discharge is the third leading breast complaint after lumps and pain, with a prevalence of 5-10% in women. […] Nipple discharge is associated with a 5-23% risk of malignancy in women, typically DCIS. […] Any discharge in a man is suspicious and associated with breast cancer in 25-57% of cases. […] Mammography should always be used as the first line examination for evaluation of suspicious nipple discharge, however sensitivity is relatively low (20-25%). […] Ultrasound should always be obtained for evaluation of suspicious nipple discharge, and is relatively sensitive and specific when compared to mammography (56% and 75% respectively). […] MRI with contrast is very sensitive and with a high negative predictive value, however there is a high false positive rate.

• #8 Implications of nipple discharge in Hong Kong Chinese women | HKMJ

  https://www.hkmj.org/abstracts/v24n1/18.htm

  Nipple discharge is a relatively uncommon complaint in Hong Kong Chinese women. According to a study in 1997, nipple discharge constituted 1.5% of all presenting complaints for women who attended a breast clinic in Hong Kong. On the contrary, nipple discharge accounted for up to 4% to 7% of all presenting symptoms in other studies. This may be better explained by the unique Chinese culture and help-seeking pattern rather than a true disease pattern. With this understanding, any clinical survey will probably underestimate the prevalence of nipple discharge in Chinese women. […] Numerous studies have demonstrated the relationship between breast cancer and nipple discharge, with malignancy reported in up to 9.3% to 21% of all patients who present with nipple discharge. The most challenging role of breast surgeons is to accurately identify these patients. Notwithstanding, controversy persists about the value and accuracy of individual investigative tools for nipple discharge.

  Nipple discharge affects over 80% of women at some point in their lives, with malignancy detected in up to 23% of cases. […] This review highlights the shift from traditional surgical approaches to advanced imaging techniques, which enhance diagnostic accuracy and reduce unnecessary procedures. […] Diagnosis begins with a thorough medical history and physical examination to assess the need for imaging. […] Physiological nipple discharge, which is bilateral, multiductal, and non-spontaneous, typically requires no imaging. Conversely, pathological nipple discharge (PND), characteristically unilateral, uniductal, and spontaneous, requires imaging to rule out malignancy. […] For women over 40 years, the first-line imaging modality is full-field digital mammography (FFDM) or digital breast tomosynthesis (DBT), usually combined with ultrasound (US).

  Discharge from a nipple in a woman who is not pregnant or breast feeding is an abnormal symptom. A study showed that about 3-9% of patients reporting to a breast clinic with a breast symptom presented with a nipple discharge. […] Nipple discharge is regarded as pathological if blood stained, serosanguinous, serous or clear. […] It has been reported that in about 5-12% of women with a bloody one breast nipple discharge there is an underlying cancer, such patients often have an associated lump. […] A discharge from the nipple of one breast that is spontaneous and blood stained should be therefore prompt a physician consultation. […] Investigation of this symptom is triple assessment: Clinical examination to look for a palpable lump, cytological testing of the discharge fluid and diagnostic imaging with a mammogram and breast ultrasound.

  Nipple discharge is a common symptom among women of reproductive age, with most women experiencing at least one episode. Although nipple discharge is predominantly physiologic or due to a benign etiology, an underlying malignancy is identified in up to 21% of patients with pathologic discharge who undergo biopsy. The initial workup includes a comprehensive history and physical examination, with the primary aim of distinguishing between normal lactation, nonpuerperal galactorrhea, and pathologic discharge. […] Pathologic discharge is generally spontaneous and unilateral, and originates from a single duct opening on a nipple. It may be bloody, serous, serosanguineous, or watery. The differential diagnosis includes intraductal papilloma, ductal ectasia, and breast carcinoma. If discharge is deemed pathologic, age-appropriate diagnostic imaging with mammography and/or ultrasonography is indicated. Studies have shown a low risk of malignancy when diagnostic studies are negative. The clinical utility of cytology is limited because of its high rate of false-negative findings. Imaging results of BI-RADS 4 or 5 require tissue biopsy. For imaging results of BI-RADS 1 to 3, management options include duct excision or follow-up with physical examination after six months and repeat diagnostic imaging for one to two years or until discharge resolves. Duct excision, potentially localized by ultrasonography, magnetic resonance imaging, or ductography, is preferred to rule out malignancy.

The risk of cancer when nipple discharge is the only symptom is fairly low. […] Nipple discharge that is due to a noncancer breast condition may be treated by keeping the nipple clean, among other treatments. Nipple discharge that occurs because of infection may need hospitalization. […] Your healthcare provider will likely want to find out if the discharge is coming from 1 duct or several. Multiple duct discharge is nearly always benign. It is likely due to changes, such as ectasia. Discharge coming from a single duct may be more significant. But if mammography shows no abnormality, surgery may not be needed. […] Nipple discharge can be different colors and textures.

  Nipple discharge is the third most common breast-related symptom (after palpable masses and breast pain), with an estimated prevalence of 5% to 8% among premenopausal women.1 While most causes of nipple discharge reflect benign issues, approximately 5% to 12% of breast cancers have nipple discharge as the only symptom.2 Not surprisingly, nipple discharge creates anxiety for both patients and clinicians. […] Although the risk of malignancy is low for all patients with nipple discharge, increasing age is associated with increased risk of breast cancer. One study demonstrated that among women aged 40 to 60 years presenting with nipple discharge, the prevalence of invasive cancer is 10%, and the percentage jumps to 32% among women older than 60.6 […] Nipple discharge can be classified as physiologic or pathologic. For pathologic discharge, a thorough physical examination should be performed with subsequent imaging evaluation. First-line tools, based on patient age, include diagnostic mammography and targeted ultrasonography. Contrast-enhanced MRI is then recommended for negative or equivocal cases. All patients with pathologic nipple discharge should be referred to a breast surgeon following appropriate imaging evaluation.

  Appropriate imaging evaluation of nipple discharge depends the nature of the discharge. Imaging is not indicated for women with physiologic nipple discharge. For evaluation of pathologic nipple discharge, multiple breast imaging modalities are rated for evidence-based appropriateness under various scenarios. For women age 40 or older, mammography or digital breast tomosynthesis (DBT) should be the initial examination. Ultrasound is usually added as a complementary examination, with some exceptions. For women age 30 to 39, either mammogram or ultrasound may be used as the initial examination on the basis of institutional preference. For women age 30 or younger, ultrasound should be the initial examination, with mammography/DBT added when ultrasound shows suspicious findings or if the patient is predisposed to developing breast cancer. For men age 25 or older, mammography/DBT should be performed initially, with ultrasound added as indicated, given the high incidence of breast cancer in men with pathologic nipple discharge.

  Nipple discharge can be a bothersome and an embarrassing symptom that affects women of all ages. Around 2 to 5% of women experience nipple discharge. Among the three symptoms discussed in this review, nipple discharge may be the most worrisome symptom for the patient and the physician seeing the patient, as in a small number of cases this can signify an underlying malignancy. Nipple discharge can be spontaneous or provoked therefore a thorough history is still most important yet simple step to correct diagnosis when assessing the patient. Nipple discharge is defined as pathological when it is unprovoked, unilateral and blood-stained, serous, watery, creamish or greenish blue. Malignancy rates in this category differ and have been reported to be anywhere from 3% (newer studies) to 23.9% (older studies). Mammography, Targeted Ultrasonography and Cytology are the main stay of diagnosis depending upon the age of the patient and frequency of discharge. Ductoscopy can be used to evaluate pathological nipple discharge and can detect up to 94 per cent of all lesions. Specificity, however, is low, and histological diagnosis is still essential. Colour alone is insufficient when determining the underlying cause, although malignancy is much more likely in patients presenting with haemorrhagic discharge. Nipple discharge cytology and marker study may aid in diagnosis, as recent studies suggest that certain tumour markers (CA15-3, CA125, CEA, TSGF) can serve as biomarkers in diagnosis and prognosis of breast cancer. Other potential biomarkers have been identified by recent studies, and include proteins of carbonic anhydrase 2, catalyse and peroxiredoxin-2. Levels of these proteins differed significantly between nipple discharge from patients with and without breast malignancy. The use of such biomarkers could facilitate and accelerate diagnostic pathways in breast clinics, making it easier to triage high-risk patients.

  The sensitivity, specificity, PPV, NPV and AUC value of LBC were higher than those of CSC, as shown by compared diagnostic consistency of the cytology examination and pathology. […] Therefore, it is necessary to combine other specific tests in nipple discharge, such as the Thomsen-Freidenreich antigen test and detection of tumor markers (CEA, CA153, miRNA, etc.). […] In conclusion, LBC can be used as a new diagnostic method for cytological evaluation using direct nipple discharge without aspiration.

  This pathway provides guidance on the imaging of adult female patients with new onset of nipple discharge. […] 97% of nipple discharge is caused by benign disease but it may be the presenting complaint for malignancy. […] These features are associated with an increased risk of malignancy and further imaging is recommended when any of these features are present. […] Malignancy occurs in 5-25% of women with pathological discharge. […] All women with nipple discharge should be assessed with the Triple Test, including examination, imaging and tissue biopsy. […] Mammography and ultrasound do not detect all lesions presenting with nipple discharge and do not reliably differentiate between malignant and benign lesions. […] Surgical referral is recommended if symptoms are persistent, despite normal investigations. […] MRI may be considered by a breast specialist in limited cases where mammography and ultrasound are negative and there is persisting clinical concern. […] Where MRI and mammogram are both negative, the risk of malignancy is low at 4% and surveillance rather than surgical excision may be suitable.

  Nipple discharge can be physiological or pathological. Physiological discharge is typically bilateral, multiductal, with a milky appearance; causes include lactation and galactorrhea. Pathological discharge is typically unilateral, uniductal, nonmilky, and spontaneous. Although most causes of pathological nonmilky nipple discharge are benign (e.g., intraductal papilloma, mammary duct ectasia), malignancy is an important consideration. The diagnostic approach to nipple discharge is based on clinical evaluation findings, including characteristics of the discharge and patient age. Further evaluation with imaging is required for all patients with red flags in nipple discharge. Treatment depends on the underlying cause. […] The following are red flag features for malignancy. […] Perform a focused clinical evaluation in all patients, including for red flags in nipple discharge. […] Biopsy is necessary if imaging findings are concerning for malignancy (e.g., BI-RADS 4 or 5). […] Treatment is based on the underlying cause; see Common causes of nipple discharge.

  Breast cancer is an uncommon cause of nipple discharge. Less than 5% of women with breast cancer have nipple discharge, and most of these women have other symptoms, such as a lump or newly inverted nipple, as well as the nipple discharge. […] Nipple discharge diagnosed as physiological discharge requires no treatment. It is important to stop expressing, or squeezing the nipple and breast, as this causes more fluid to be made. […] Nipple discharge that is spontaneous, blood-stained, persistent, and unrelated to pregnancy or breast feeding needs to be investigated further. This investigation will include clinical examination by a doctor, and imaging of the breast with a mammogram and/or breast ultrasound.

  According to Morrogh et al., the gold standard approach to treating patients with pathological nipple discharge is surgical duct excision; however it is a significant surgical intervention and distinguishing between a patient with pathological and a patient with physiological nipple discharge is essential in this case. A treatment algorithm has been previously suggested by Gray et al., It is a useful algorithm, which concisely summarises management methods depending on the examination and investigation findings. It suggests that only patients with high risk of carcinoma or those who are unwilling to accept regular follow-ups should be considered for duct excision. This prevents unnecessary radical treatment and formulates a clear plan for patients who are at lower risk and do not need significant surgical intervention. If a mass can be palpated, a biopsy should be taken. If no mass can be identified, sub-areolar exploration may be considered, although practices differ across different health boards. Authors prefer to do Micro-dochotomy in case of persistent haemorrhagic or profuse discharge from single duct and Major Duct Excision (Hatfields operation) when multiple ducts are involved. If a duct papilloma is identified then a wire guided excision biopsy is recommended by the Association of Breast Surgeons (ABS) in the UK. Both of these procedure are intermediate grade operation and the patient can be treated as day case. The advantage of the operation, whether single duct Microdochotomy or Major Duct excision, are relief of symptoms and the definitive histological diagnosis of the cause of nipple discharge.

  Nipple discharge is the third most common breast complaint after breast pain and breast mass. Fifty percent to 80% of women in their reproductive years have nipple discharge, and 6.8% of these are referred to a breast surgeon. Most nipple discharge is benign in origin (97%). […] The clinical history is most helpful in distinguishing benign from suspicious or pathologic nipple discharge. The patient’s age is very important, as women greater than 40 years of age are at higher risk of having pathologic discharge. Postmenopausal women with nipple discharge are rarely benign. […] The primary goal of evaluation of the nipple discharge in a general outpatient setting or the emergency department is to distinguish patients with benign discharge from those with underlying breast cancer, infection/abscess, or those patients who are at high risk of developing pathologic processes.

  Nipple discharge is the third most common breast-related complaint, after breast pain and breast mass. During their reproductive years, up to 80 percent of women will have an episode of nipple discharge. […] Most nipple discharge is of benign origin. The primary goals of evaluation and management are to differentiate patients with benign nipple discharge from those who have an underlying papilloma, high-risk lesion, or malignancy and to manage patients with underlying pathologic nipple discharge. […] The types of nipple discharge and how to evaluate and manage this common problem will be reviewed here. The surgical management of pathologic nipple discharge is discussed in a separate topic. […] Nipple discharge is categorized as normal milk production (lactation), physiologic nipple discharge (galactorrhea), or pathologic (suspicious) nipple discharge based on the characteristics of presentation.

  Nipple discharge affects over 80% of women at some point in their lives, with malignancy detected in up to 23% of cases. […] This review highlights the shift from traditional surgical approaches to advanced imaging techniques, which enhance diagnostic accuracy and reduce unnecessary procedures. […] Diagnosis begins with a thorough medical history and physical examination to assess the need for imaging. […] Physiological nipple discharge, which is bilateral, multiductal, and non-spontaneous, typically requires no imaging. Conversely, pathological nipple discharge (PND), characteristically unilateral, uniductal, and spontaneous, requires imaging to rule out malignancy. […] For women over 40 years, the first-line imaging modality is full-field digital mammography (FFDM) or digital breast tomosynthesis (DBT), usually combined with ultrasound (US).

  Nipple discharge is the third most common breast-related symptom (after palpable masses and breast pain), with an estimated prevalence of 5% to 8% among premenopausal women.1 While most causes of nipple discharge reflect benign issues, approximately 5% to 12% of breast cancers have nipple discharge as the only symptom.2 Not surprisingly, nipple discharge creates anxiety for both patients and clinicians. […] Although the risk of malignancy is low for all patients with nipple discharge, increasing age is associated with increased risk of breast cancer. One study demonstrated that among women aged 40 to 60 years presenting with nipple discharge, the prevalence of invasive cancer is 10%, and the percentage jumps to 32% among women older than 60.6 […] Nipple discharge can be classified as physiologic or pathologic. For pathologic discharge, a thorough physical examination should be performed with subsequent imaging evaluation. First-line tools, based on patient age, include diagnostic mammography and targeted ultrasonography. Contrast-enhanced MRI is then recommended for negative or equivocal cases. All patients with pathologic nipple discharge should be referred to a breast surgeon following appropriate imaging evaluation.

  PND is a clinical diagnosis that warrants a thorough work-up, not only because of the risk of malignancy, but also because of the concern it causes patients. Mammography should be the initial study in women 40 years of age or older and men 25 years of age or older. […] The risk of malignancy in patients who are evaluated surgically ranges from 5-23% of cases with predominantly ductal carcinoma in situ, but also invasive cancer. […] Therefore, ruling out malignant lesions should be the primary aim in patients presenting with PND. […] Patients with PND have traditionally been considered for surgical excision of the involved duct, however, there has been a management shift towards observation in low risk patients. […] Surgical intervention for PND is comprised of either total subareolar duct excision or selective duct excision of the affected duct.
