Why do I have a lump in my breast?

It depends! Not breastfeeding or recently pregnant? Over the age of 40? Had the lump for more that 1-2 months? See your doctor! If you are recently pregnant or breastfeeding, under the age of 30, and only noticed it recently, start taking an NSAID (otc Ibuprofen or naproxen), eliminate caffeine, and give it a few weeks to see if it resolves. If not, again, see your doctor.
Pay it attention. If you are breastfeeding and it is painful, this may be a blocked duct. Massage it, add a warm compress, take some Ibuprofen (with food), and continue to express your milk. If any worsening occurs, redness around the area, increase in size, and/or fever, see your doctor for a further evaluation.

Fibroadenoma. The most common breast tumor is a fibroadenoma. This is a benign tumor which may be present as early as the teen years. As women age, breast cysts may develop, which are benign fluid-filled lumps (peak incidence ages 35-50). It is often very difficult to distinguish a lump from normal "lumpy-bumpy" tissue. When in doubt, it is best to see your primary care physician or gynecologist.

HIghly unlikely. If done with sterile precautions. However, the armpit lymph nodes connect to those along the sub clavicle vein nodes and then into the neck. If the lump was cancer, you will need to have sentinel nodes checked, and if these neck nodes do not subside, they too need biopsy.

Had a biopsy on left breast lump last year, got diagnosed with fibroadenoma, can it cause pain? An little swelling

Sometimes yes. If a core biopsy made the diagnosis, I would repeat an ultrasound, to see if the fibroadenoma grew. Even though benign, fibroadenomas can grow. If the growth is substantial, I would recommend removal, to r/o a phyllodes tumor. This is a tumor w malignant potential that can be difficult to distinguish from a fibroadenoma on core biopsy.
Fibrous demons. Those lumps are sometimes tender to touch they are usually benign. Excessive caffeine intake can make them more prone to happen.
Possible. Fibroadenoma of breast most of the time painless or will give minimum discomfort, if you have only biopsy and tumor is not removed completely may cause pain due to tissue reaction & scar tissue then get it removed, if removed go back to your surgeon for evaluation possible tests.
It may. Your breast fibroadenoma maybe enlarging. However, there may be other causes for your breast pain and swelling. I would suggest that you have a medical evaluation.
Yes, a fibroadenoma can enlarge and/or cause pain. But at this point you don't know if the fibroadenoma is causing your new symptoms, so you need to see your doc for an evaluation.
