Colorectal cancer symptoms

In the early stages of the disease, colorectal cancer symptoms may be minimal, or not present at all. As the disease progresses, symptoms may increase in quantity and degree of severity. Because colorectal cancer symptoms often do not present themselves until the disease has progressed past the initial stage, regular screening is recommended, and should be part of a continued health plan for anyone over 50. If you are under 50 and have a family history of colorectal cancer or other risk factors, you should talk with your doctor about when you should start regular screening.

Metastatic colorectal cancer symptoms

Metastatic colorectal cancer symptoms depend on where the cancer has spread, as well as the size and location of the tumor within the body. Patients with metastatic colorectal cancer will not always notice symptoms before a diagnosis. Symptoms depend on a number of factors, listed below.

  • If the bones are affected, symptoms may include pain, fractures, constipation or decreased alertness due to high calcium levels.
  • If the lungs are affected, symptoms may include shortness of breath or difficulty breathing, coughing, chest wall pain or extreme fatigue.
  • If the liver is affected, symptoms may include nausea, extreme fatigue, increased abdominal girth, swelling of the feet and hands due to fluid collection and yellowing or itchy skin.
  • If the lymph nodes of the abdomen are affected, it may cause bloating, a swollen belly or loss of appetite.
  • If the brain or spinal cord is affected, symptoms may include pain, confusion, memory loss, headache, blurred or double vision, difficulty with speech, difficulty with movement or seizures.

Treatment options for metastatic colorectal cancer

Treatment options may vary depending on where the cancer has spread, but they may include surgery, radiation therapy, chemotherapy and/or targeted therapy

Understanding cancer symptoms
