It is quite unlikely that you have breast cancer, but its not impossible.
20 year olds don't even show up in this chart, but for a 30 year old, about 3 to 4 out of 1000 women who are now aged 30 will get breast cancer by the time they reach 40 years old. www.cdc.gov/cancer/breast/stat... Another source said worldwide, the chance of a 20-29 year old woman to get breast cancer is about 1 in 2000. http://www.worldwidebreastcancer.com/learn/breast-cancer-statistics-worldwide/
Was your grandmother's breast cancer premenopausal, or before the age of 50? Even if your grandmother was <50 years old at diagnosis, if there were no other cases of breast or ovarian cancer in your 1st or 2nd degree relatives, then you probably wouldn't trigger this USPTF guidelines for BRCA testing. www.uspreventiveservicestaskfo... In any event, only about 5-15% of breast cancers are thought to be from a single hereditary mutation.
Survival chances are very hard to predict, because it depends on a lot of different factors, including if you have involvement of the lymph nodes, 'personality' of the cancer, etc. But to give you some sort of number, this chart, which is VERY OLD, thus treatments are OUT OF DATE (This data is about from 1988 to 2001), says that in general 2 cm tumors have about an 88% survival rate (last page). seer.cancer.gov/publications/survival/surv_breast.pdf
So, unless you have a lot of undiscovered first degree relatives that had breast or ovarian cancer, or you have a history of radiation TREATMENT to the chest, such as for Hodgkin's disease or lived near Chernobyl nuclear plant, then I'd say your chances of having breast cancer are quite low.
Its natural to be scared when you are ruling out something that can threaten your life. But I still encourage you to keep your appointment and get it checked out. You may learn some things about your breasts. Benign lumps or cysts are very common in young women.
Feel free to ask questions or vent, OK?
