This is Dr. David
I am a cancer doctor
routine blood tests are not a good way to detect cancer in the body.
at his age, lung cancer and breast cancer are still very rare and unlikely.
he should quit smoking at this point.
there is a very very small chance he could have a primary breast cancer causing a lump in his breast. but this is very rare.
usually male breast cancer will cause blood to come from the nipple.
when is his breast biopsy?
what other questions do you have?
google is not a good idea
it could be a blocked breast duct in his breast causing the mass.
what he needs a breast ultarsound which can tell more information and see if it looks like a blocked breast duct or invasive breast cancer.
much more likely to be a blocked breast duct.
try some warm compresses or warm towels on the breast and see if that helps.
let me know if you have other questions.
