Breast self-exam (bse) is an important defense in the early detection and prevention of breast cancer. bse should be performed:

Breast self exams should be performed once a month, this way you can familiarize yourself with how your breasts normally look and feel. You should examine yourself several days after your period ends, when your breasts are least likely to be swollen and tender.

for me i have felt invisible when i was clearly struggling,or,i made a great achievement ,and,nobody took to notice me either because they just didn't see it,or,people just turned their back on me.i can see a person being invisible by choice,or,without choice like i did.the people who are invisible by choice don't try to talk to people,don't try to make friends,and,keep to themselves.i haven't been one of those people so i couldn't give you a reason.

hope this and can i get bainliest my dude : d
