What are the main symptoms of cancer which I should look for.
The symptoms vary from cancer to cancer but these are some of the more general ones: unusual growths or lumps, unexplained weight loss, loss of appetite, a sore or ulcer that will not heal, nagging cough or hoarseness, coughing up blood, a mole that bleeds or changes shape, unexplained changes in bowel or bladder habits, unusual discharges, recurrent pain in any part of the body.
