Hi olive it's entirely up to you but I would definitely get checked it won't do any harm. After my diagnosis I would always get lumps and bumps assessed to be on the safe side and encourage others to do so.

Hope you get it sorted and hopefully it turns out to be nothing which many do.

take care love Kiera xx

Hello and thanks for your post,

I can understand that finding a lump can be worrying and we would always advise anyone to get any new lump checked out by their doctor. You could also ask your GP to check the lump under your arm.

Cancer at your age is unlikely but we are unable to diagnose you. Breast cancer is  usually a cancer of women much older then yourself. Benign (non cancer) lumps are much more common at your age. You can read much more about these on the Breast Cancer Now website here

I hope you manage to speak to your GP soon and hopefully they will be able to provide you with that reassurance.

All the Best,

Catherine
