Hello,
Thanks for posting your query.
A soft painless mobile lump in the armpit is not likely to be a cancer. It is most likely a benign swelling.
Usually these are a collection of fat cells forming a lipoma. You can get it removed surgically if it is bothersome and disfiguring.
In case there is a sudden change in its size and shape or color or it becomes painful then you must seek a medical advice from your physician after proper examination.
I hope this answers your query effectively.
In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out.
Please accept my answer in case you do not have further queries.
Wishing you good health.
Regards.
