How do cancers start?

Doctor 1

Answered by 1 Apollo Doctors

The cause of cancer is multifactorial such as genetics, environmental and lifestyle. 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 which may form a mass of tissue called a tumor.

I've noticed something concerning lately there's a lump under my arm, and it's been there for a couple of months now. It seems to come and go, and sometimes it gets bigger before shrinking again after a few days. It's pretty soft to touch, but now I'm starting to feel something similar in the other armpit too. Should I be worried about this? What could it possibly be?

Observe the Lumps: If they continue to grow, cause pain, or do not go away, you should consult a doctor for a proper diagnosis. Medical Evaluation: A healthcare professional may want to examine the lumps physically, and potentially order an ultrasound or biopsy to rule out other conditions, particularly if you're concerned about the lumps appearing in both armpits. Watch for Changes: If the lumps become painful, larger, or change in appearance (color, warmth, etc.), it's important to seek medical attention quickly.

I'm feeling anxious about a hard lump I've noticed in the upper left area of my chest, close to my left breast. It feels almost like a bone or something solid just beneath the skin. Whenever I touch it, I'm reminded of how hard it is, and it's got me pretty worried. Could it be something serious? What might be causing this?

Surgeon opinion is advised to the patient. USG of the lump,FNAC and microscopy for mitotic cells , biopsy and complete blood count ,esr and C-reactive protein is advised to the patient.
