  As colon cancer progresses to stage II and stage III, the tumor has grown larger and may have begun to invade nearby tissues or lymph nodes. At this point, colon cancer symptoms become more noticeable and harder to ignore. Common symptoms during these intermediate stages include: Rectal bleeding or blood in the stool: One of the most common and alarming symptoms of colon cancer is rectal bleeding or finding blood in the stool. The blood may appear bright red or dark and tar-like, depending on its location in the colon.

Persistent abdominal pain: The abdominal discomfort that was mild in earlier stages may become more persistent and intense. Pain can be localized or spread across the abdomen, and it may worsen after meals. Unexplained weight loss: Sudden, unintentional weight loss can be a sign that the body is using more energy to fight the tumor. Patients may notice a significant drop in weight without changing their diet or exercise habits.

  Abdominal pain is present in 20% of cases. Partial large-bowel obstruction may cause colicky abdominal pain and bloating. Back pain is usually a late sign caused by a tumor invading or compressing nerve trunks. Urinary symptoms may also occur if the tumor is invading or compressing the bladder or prostate. Pelvic pain is a late symptom, usually indicating nerve trunk involvement, and is present in 5% of all cases. […] Malaise is a nonspecific symptom and present in 9% of rectal cancer cases. Bowel obstruction due to a high-grade rectal lesion is rare, occurring in 9% of all cases. Other manifestations include emergencies such as peritonitis from perforation (3%) or jaundice, which may occur with liver metastases (1%). […] The rising rates of colon and rectal cancer in persons younger than 50 years has prompted research in this population. A matched case-control study of 5075 incident colorectal cancers in patients younger than 50 years identified abdominal pain, rectal bleeding, diarrhea, and iron deficiency anemia within three months to two years before diagnosis as red-flag clinical manifestations in this age group. The presence of any one of those clinical manifestations was associated with 1.94-fold higher risk; any two, with 3.59-fold higher risk, and three or more, with 6.52-fold higher risk. The risk associations were stronger in younger patients and with rectal versus colon cancer.

  Colon and rectal cancers together are the third most commonly diagnosed cancer in the United States and the second deadliest. Rectal cancer has distinct environmental associations and genetic risk factors different from colon cancer. The transformation of the normal rectal epithelium to a dysplastic lesion and eventually an invasive carcinoma requires an accumulation of genetic mutations either somatic (acquired) and/or germline (inherited) over an approximately 10 to 15 years period. Tumor regression grade after pre-operative therapy and pathological staging are the most important prognostic indicators of rectal cancer. […] A careful history and physical examination, including a digital rectal exam, are paramount on clinical suspicion. An endoscopy examination with rigid sigmoidoscopy is required to measure the distance from the lesion to the anal verge (less than 15 cm) and for tissue biopsy for pathological confirmation of rectal cancer.

Stage 1: The tumor grows below the lining and possibly into your rectal wall. Stage 2: The tumor grows into your rectal wall and might extend into tissues around your rectum. Stage 3: The tumor invades your lymph nodes next to your rectum and some tissues outside of your rectal wall. Stage 4: The tumor spreads to distant lymph nodes or organs.

  Symptoms according to tumor location on the clinical presentation of rectosigmoid are more frequently associated with a change in bowel habits (diminish stool caliber), bright red blood per rectum (hematochezia), pain (tenesmus), leakage diarrhea (mucus discharge), and constipation (obstruction). Late symptomatic presentation of metastatic disease at diagnosis will depend on the affected organ according to the dissemination route. […] All newly diagnosed patients with rectal cancer should be universally screened for DNA mismatch repair/microsatellite status present in up to 13% of all sporadic rectal cancer cases. […] The overall 5-year survival rate for rectal cancer is 67%, but this is affected significantly by various factors, most notably the stage of cancer. If the cancer is diagnosed when it is in the localized stage, the survival rate jumps to 89%. The 5-year survival rate is 71% if cancer has metastasized to surrounding tissues or organs and/or the regional lymph nodes. However, with metastatic spread to distant areas of the body, the 5-year survival rate drops to 15%.

  By the time colon cancer reaches stage IV, it has spread to other parts of the body, most commonly the liver, lungs, or distant lymph nodes. At this advanced stage, colon cancer symptoms are typically severe and can affect multiple systems in the body. Severe abdominal pain and discomfort: As the tumor grows and potentially obstructs the colon, the pain can become intense and continuous. Patients may also experience severe bloating and difficulty passing gas. Chronic constipation or bowel obstruction: In some cases, the tumor can cause a complete blockage of the colon, resulting in an inability to pass stool. This is a medical emergency and requires immediate attention. Jaundice: If the cancer has spread to the liver, patients may develop jaundice, which causes yellowing of the skin and eyes. Jaundice occurs when the liver is unable to properly filter waste products from the blood. Difficulty breathing: If the cancer has metastasized to the lungs, patients may experience shortness of breath, chest pain, or a persistent cough. Fatigue and weakness: As the cancer spreads, the body becomes increasingly fatigued, and patients may feel weak and lethargic even after rest.

[…] The analysis showed that, in the period of 3 months to 2 years before people with colorectal cancer were diagnosed, four signs were more commonly reported in people who developed colorectal cancer than in matched controls: abdominal pain, rectal bleeding, diarrhea, and iron deficiency anemia. […] Having just one of these signs during this period was associated with nearly twice the likelihood of being diagnosed with early-onset colorectal cancer as having none of the signs. […] Having three or more of these signs was associated with six times the likelihood of being diagnosed with the disease.

  By the time colon cancer reaches stage IV, it has spread to other parts of the body, most commonly the liver, lungs, or distant lymph nodes. At this advanced stage, colon cancer symptoms are typically severe and can affect multiple systems in the body. Severe abdominal pain and discomfort: As the tumor grows and potentially obstructs the colon, the pain can become intense and continuous. Patients may also experience severe bloating and difficulty passing gas.
