Sir/madam

My sister is 26 years old. She has a lump under her armpit on both sides but the right side is much bigger.During the last 4 years its size has been increasing, even thuogh she didn't feel any pain but it become bigger and bigger.We even went to doctor 2 years back but the general surgeon told us that its simple nothing wrong in it. However they didn't advice us to unergo any kind of test.They just check externally and told not to touch it regularly.Please advice us what it may be we are afraid that what it could be cancer.

thank you

If you are worried about i'd see a doctor who WILL refer you to someone who will do tests. Blood tests and x-rays at the least.

Don't let them tell you otherwise doctors get lazy too and its not right.
