Less Likely: I think you should speak to your MOm right away and let her know what is happening to you. There are many other causes of a swollen lymph node in the arm pit (axilla) including and infection that needs treatment with an antibiotic. The less likely cause is a "cancer".

Need to examine: If is not feasible to know what you are feeling. You may be feeling a rib rather than a mass in the breast. It would be prudent to see your doctor for an evaluation. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more

I have a lump in my armpit it's painless an its been there for a few months. I think it could be cancer.

I bet it's not: If it starts growing or gets stuck to your nearby structures, get it seen. Otherwise, it's probably just the axillary lymph node that many of us have, especially if at some time you had an infection or contact dermatitis on that extremity and it got a little bit scarred up. Glad you're a good observer of your body. ...Read more

You are right: Cancer commonly is a painless bump/lump. But some tumors can be tender. Armpit is prone to get infection in the hair follicles which can produce a red, tender painful lump but it usually settles down in one to two weeks. Breast cancer, of course can spread to the lymph nodes of the armpit and produce a firm, painless lump there. That is what you need to be sure about. ...Read more

I have a small lump under my right armpit. Its been there for 2 months. It was painful initially, but not anymore. I am a 24 year old male. Cancer ?

Not likely: Infection or inflammation of anytime can produce a painful lump. This seems to be the case with your lump under the arm. The fact it is now painless indicates that acute problem has settled down. But watch its size...Which should get smaller and not be increasing at all.If it is increasing in size, then you need to see a doctor for further examination to find out its nature. Cancer is unlikely rig. ...Read more

I had a lump in my armpit for one year. it was very small and pain free.now in 2 days it has become enlarged, swollen and very painful. is it cancer?

Probably not: If you're a 24 year old male, it's extremely unlikely that you have a cancer causing a lump in the armpit. It is much more likely that it is a subcutaneous abscess. The proper treatment for something like that is I&D (incision and drainage). This can be done under local anesthesia in a doctor's office, preferably either a dermatologist or a general surgeon. ...Read more
