She's having pain in her left breast since 1 month. Sometimes pain also occurs in the right one too. (She's 20 years old)
The pain starts anytime
Mostly when she lays on bed.
Today she faced an unbearable pain for 10-15 minutes near her left nipple.
Her left breast mostly stays hard.
She's not comfortable to share this with her parents.
So she shared with me.
Now please tell me what could be the reason of her pain?
She is 20 years old
If she is worried about cancer, this surely isn't cancer at all, tell her not to worry.
As for pain, there are multiple causes, including PMS (Pre menstrual syndrome), hormonal changes, minor infections etc. One would need to assess her and understand her complaints to give some medicines.
Ask her to take pain killers for a day. And if it doesnt settle, preferably just show to a doc. It will surely settle down, but its essential to take the right advice hence to see a doc.
Thankyou so much sumeet_shah
She's 20 years old.
Nd she's worried.
So which painkiller will u prefer?
I'll tell her to take a dose of that painkiller if it doesn't settles I'll definitely take her to the doc
As doctor Shah said, your friend's pain is probably nothing, but having it checked will give her peace of mind. When I was in my early 20s I had a large lump appear in one breast. I was sure that it was breast cancer and that it was going to kill me, but also did not want to worry my parents. It turned out to be a fluid filled cyst. My doctor drained it and that was the end of it.
I did tell my mother. I hope your friend can talk with her mother, also. It could be that she had the same issue when younger, and could share that with your friend. Meanwhile, she is lucky to have your support.
