Its my first day of my period and its a very heavy flow its never been like that ever. last month it was heavy for the first day. then again today its very heavy is that normal or sign of cancer? thank you!?

No, that's for sure not the common sign of cancer. Most people have heavy period on the second day but it could be normal if the first day is heavy but it lightens up the next day. However, if your period is heavy every day and it is quite change from 2, 3 months ago, you may have some hormonal imbalance and you should see a GYN doctor. Abnormal bleeding from other diseases can occur in any day.

Agree with Dr. Le. You should take oral iron and multivitamins to prevent anemia from blood loss. Your doctor can prescribe pills that can limit your period to once a year. Wish you good health!
