How do cancers start?

Doctor 1

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 really worried and need some guidance. I've been dealing with pain and a burning sensation in my right nipple for about 45 days and mild pain in my right armpit for a few days. I've taken a lot of medicine, but nothing seems to help. I had a mammogram and an ultrasound done; the mammogram was all clear, but the ultrasound showed a well-defined oval hypoechoic lesion measuring 63 mm in the 34 clock position of my right breast. It also noted some bilateral axillary lymph nodes with preserved fatty hila that they said were insignificant. I also had my right ovary removed because of a dermoid cyst, and my left ovary is normal in size but shows multiple peripherally arranged follicles, and they said it appears polycystic. I'm really anxiouscould this possibly be cancer?

Based on your symptoms and test results, it's unlikely to be breast cancer, given the clear mammogram and ultrasound findings describing a small, well-defined hypoechoic lesion, which may be a benign cyst or fibroadenoma; however, the persistent nipple pain and burning warrant further evaluation by a breast specialist or a multidisciplinary team to rule out other conditions like ductal ectasia, periductal mastitis, or hormonal imbalances, which may be related to your history of ovarian issues, including the removed dermoid cyst and polycystic-appearing left ovary.

I'm feeling a bit concerned because I've noticed a lump next to my right nipple that moves around and is slightly painful. I've had similar lumps on my thighs before. About ten months ago, I had a chest CT scan after having COVID, and everything was clear. Could this lump be dangerous?

if it is lump in the breast do one ultrasound as soon as possible

My whole family has been dealing with a viral cold and flu. Now my mom's got it too, and she's dealing with a blocked nose and body aches. Her PET scan is scheduled for tomorrow to check if the lung tumor and nodules are active. Is it a good idea to take her for the scan while she's feeling like this, or should we think about rescheduling?

they can undergo pet scan
