I would definately get it checked , I'm sure its probably nothing to worry about but better to have it confirmed.

I have been diagnosed with breast cancer and did feel some thickness but not a lump it was then picked up on a mamogram.Luckily mine is treattable but I could have got it checked earlier.(not saying this is likely to be ) but I wasn't sure what I was supposed to be checking and a professional will show you.

You will feel better once you have got it checked x 

Hello and thanks for posting, 

Breast cancer in women of a young age for example, is rare, so for this reason alone another explanation for this is much more likely. The way our breast tissue feels and looks, can be influenced by our hormones which change over the month of our menstrual cycles. So see if there is a pattern to it. Weight gain/loss can affect breast appearance too. 

Googling doesn't tend to help overall, so for peace of mind, do ask your GP about it, and they can advise you further.

Wishing you the best,
