 Hi, I am Dr. Ashwin Rajgopal. I am the consultant surgical oncologist at Manipal Hospital, Whitefield. There are a few warning signs in cancer which everybody should be aware of. If any person is has any lump in the body, if they are having any sore throat or having any sore ulcer in the mouth or any person having a few bleeding well passing motion or having any bleeding in the cough on the sputum or any lady who is having excess spotting or excessive bleeding while having their cycles and person who are having excess weight loss even though they are eating regularly, these are the few warning signs which any person should be aware of and they have to come to their oncologist immediately.
