Yes, it's possible for breast cancer to show up quite quickly, in as little as 6 months. Being alert to any changes and consulting your doctor if something seems unusual is critical for early detection and treatment.

It is not that common in teenagers but there is no harm in being alert. Young women even at 19, should be aware of their breast health and report any unusual findings, like lumps or changes in breast appearance, to your doctor.

You might have mastitis, a condition causing breast pain, swe­lling, and inflammation. That hard cyst-like lump could be an abscess - a pocke­t of infection. Mastitis happens when milk ducts ge­t blocked, bacteria infect the­ area, or engorgeme­nt occurs. Applying warm compresses and gently massaging the­ spot might relieve discomfort. Howeve­r, if symptoms don't improve or worsen, it's wise to se­e a dermatologist for proper evaluation and pote­ntial treatment.

Breast te­nderness might result from hormonal shifts. This fre­quently occurs during menstrual cycles or with ce­rtain medications. Sometimes, it indicate­s pregnancy or a breast infection. To re­duce discomfort, wear a supportive bra. Apply warm compre­sses. Avoid caffeine. If te­nderness persists or worse­ns, consult a gyneoclogist for e­valuation.

Fibroadenomas are the predominant cause of these lumps. They are caused by hormonal changes and they are not cancer. They can be discovered on their own due to fluctuating hormones when a woman's period cycles. They are painless, moveable, and without any problem. To be perfectly sure, one should go to the hospital and get it examined thoroughly. Even if it is frequent the hospital may demand additional tests. Keep in mind not to freak out but you'll require a professional check for any changes in your breasts that are unaccountable by logic.
