Obese people are at the greater risk for developing any type of cancer, than the people with normally balanced weight are.
But having a risk, doesn't mean you'll develop the cancer.
Having a family history of colon cancer, having colon polyps, are main risk factors for having a colon cancer.
The type of diet is important factor, too.
Eating meat, especially processed meat in large quantities increases the nitrate amounts in your colon, which is linked with greater risk for developing colon cancer.
On the other side, eating vegetables and fruits, helps eliminating those harmful materials from your colon, decreasing the chances for having a colon cancer.
Drink plenty of water, too!
There is a small difference in colon cancer symptoms, depending on which parts of the colon are affected.
Usually, you'll noticed changed frequency and consistency of bowel movements, like constipation and thin pencil like stools.
Abdominal cramps, sense of fullness, vomiting, loss of appetite, feeling fatigue, intermittent mild rectal bleeding, gas and bloating are colon cancer symptoms.
Not intended weight loss, appetite loss due to sense of fullness, feeling tired are worrisome symptoms.
Best wishes!
