What is Rectal Cancer?
Rectal Cancer is a type of cancer that occurs in the rectum, the last six inches of the large intestine. While the cause of it is unknown, it is common to see rectal cancer in older patients and/or those who have a family history of colorectal cancers Symptoms
Abdominal pain: Discomfort or cramping in the lower abdomen may occur as the
cancer affects the surrounding tissues and organs.
Weakness/ fatigue: Often due to the body's response to cancer or anemia from blood loss.
Unintentional Weight Loss: May occur due to the body's increased energy usage
in fighting the cancer, or because of a decreased appetite.
Diarrhea or constipation
Blood in stool: Can indicate bleeding from the rectum or colon.
If cancer spreads:
Fatigue
Bone pain: Pain in the bones if the cancer spreads to the skeletal system.
Shortness of breath: Difficulty breathing if the cancer spreads to the lungs.
Loss of appetite
Jaundice: Yellowing of the skin and eyes, which can occur if the cancer
spreads to the liver.
Cough: Persistent cough if the cancer affects the lungs.
Swelling hands and feet: the cancer affecting the body’s fluid balance.
Blurred vision: Changes in vision might occur if the cancer spreads to the
brain or affects neurological function.
Risk Factors
Recurring colorectal cancers: Those who have had rectal cancer previously are at higher risk due to potential residual cancerous cells or genetic particles.
Family history of colorectal cancers: Genetic factors and shared environmental exposures can contribute to the development of the disease.
Individuals with type 2 diabetes: Possibly due to insulin resistance and higher insulin levels, promoting cancer cell growth.
Heavy alcohol drinking:Alcohol can irritate the intestines and affect nutrient absorption, increasing cancer risk.
Low vegetable diet: Diets low in vegetables may lack essential nutrients and fibers that help protect against colorectal cancer.
Older age: Natural aging may affect cell repair mechanisms.
Smoking: Chemicals in cigarettes can develop cancer cells in the rectum.
Little physical activity: Can lead to obesity and other conditions that increase the risk of colorectal cancer.
