little lump under armpit

hi! i have a little pea sized lump in my armpit. for about a months or 2, can't remember exactly. it is close to where the arm joines the chest but in the armpit. it is not painful, maybe when i touch it too much it becomes sensitive. i am 19 weeks pregnant as well. went to gp who felt it and said it is probably cyst asked me to come back in 1 month if it grows bigger. but i am still worried, could it be cancer? it is close to the surface of the skin, but there is nothing on the skin surface. and anyway it goes deeper than just surface it gets 'wider' the deeper you go and as if attached to the muscle. but you can feel it close to the sin surface. i have the impression the gp didn't care and maybe because of budget consideration they do not like to send you for tests. but how about my piece of mind??? should i check it further?

This kind of bump can be a swollen lymph node or a sebaceous cyst or a boil. Lymphadenopathy (swollen lymph nodes) is usually caused by a viral or bacterial infection along with other numerous causes.
Sebaceous cyst is a closed sac or cyst below the surface of the skin that fills with a fatty white, semi-solid material called sebum produced by sebaceous glands of the epidermis. It is usually painless but can become painful if infected.Then antibiotics are needed.

If  the symptoms do not improve then please get a clinical examination done by a dermatologist.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
