BJ, lumps that turn out to be cancer often aren't painful; the only way youknow they're there is that you can feel the mass. On the other hand, a painful lump doesn't necessarily rule out that it's cancer. Any new lump that doesn't come and go with your menstrual cycle should be checked out. I'd suggest you call for an appointment to set your mind at ease. Best wishes- PJH
I had a very painful mass (4-5 cm) in my left breast - lower part and it was cancer. Please get it checked out asap!!! It may turn out to be a fibroid or something else, but get it checked.
I agree withn Lolo, my lump was kinda painful and it was only 2cm. Lumps vary greatly - sometimes it's something and others it's nothing. Best to get it checked and put your mind at ease.
Best of luck!
