causes and symptoms of Colorectal Cancer
Answers
Answer:
Colorectal cancer, also known as bowel cancer, colon cancer, or rectal cancer, is any cancer that affects the colon and the rectum.
The American Cancer Society estimate that about 1 in 21 men and 1 in 23 women in the United States will develop colorectal cancer during their lifetime.
It is the second leading cause of cancer death in women, and the third for men. However, due to advances in screening techniques and improvements in treatments, the death rate from colorectal cancer has been falling.
Colorectal cancer may be benign, or non-cancerous, or malignant. A malignant cancer can spread to other parts of the body and damage them.
Symptoms of colorectal cancer include:
changes in bowel habits
diarrhea or constipation
a feeling that the bowel does not empty properly after a bowel movement
blood in feces that makes stools look black
bright red blood coming from the rectum
pain and bloating in the abdomen
a feeling of fullness in the abdomen, even after not eating for a while.
fatigue or tiredness
unexplained weight loss
a lump in the abdomen or the back passage felt by your doctor
unexplained iron deficiency in men, or in women after menopause
Most of these symptoms may also indicate other possible conditions. It is important to see a doctor if symptoms persist for 4 weeks or more.
