Thanks for using Health Care Magic Forum,
There is nothing to be panic .. Relax yourself . Do not be under stress .. Now your doctor found some mass in rectal examination
so I advice you to perform Colonoscopy
Examination as it says 100 percent correct diagnosis at the early stage.
Check for Hemoglobin
level as you are in periods and in loss of blood by passing motion too.
Drink plenty of fluids and prevent furthur constipation
Increasing the consumption of whole grains, fruits and vegetables, and reducing the intake of red meat
Vitamin D intake is associated with a lower risk of colon cancer
I Hope I Provided Useful Information. Do ask Furthur Questions to help You get well soon.
