Should I be concerned? Solid growing painless mass in armpit, been there 1 1/2 years. Only had an 2 ultrasounds that confirmed it's solid and growing but doc said not to worry and sent me home. The Ultrasound tech said it's soild and has tripled in size in 1 year.
It doesn't hurt but cancer runs in my family, but not breast cancer. The tech comfirmed that it isn't water filled so it's not just a cyst and it is getting deeper. Not sure if I should just trust the doctor and let it go, or insist on a biopy.
