Aetiology and risk factors for Ca colon and CA rectum

The aetiology and risk factors for both Ca colon and CA rectum are same

Aetiology

☹- SAD
S- smoking
A- alcohol
D- dietary factors (red meat is bad, fibre is good)

Risk factors

Familial polyposis coli
IBD – ulcerative colitis
Adenomatous polyp
Colorectal family

Old age ,obese and lack of physical activity predispose to cancer colon and rectum

Apart from these general aetiology for cancer such as genetics , family history etc

For both of these answers imagine an american old obese man who is smoking and drinking and eating beef burger (red meat) on a couch.
