Answered by 1 Apollo Doctors

Cancer develops when the body's normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells.

I'm 32 and have a cyst in my left breast. After seeing a doctor, they said it's fibroadenosis and mentioned surgery as a treatment. I'm really unsure about having surgery. Are there other options besides surgery that I could consider? And if I do go through with surgery, what kind of impact might it have on me? I'm a bit worried about these next steps.

Fibroadenosis is a benign condition, and in many cases, surgery may not be necessary. Non-surgical treatments, such as monitoring, medications for pain relief, or changes in lifestyle, are options to manage the condition. If surgery is recommended, it is generally safe, but its important to discuss any potential risks or concerns with your doctor for personalized advice.

Spindle tumors recurring in spine may indicate malignancy or aggressive behavior; see an oncologist urgently for imaging, biopsy, and plan for chemo or radiotherapy.
