Try not to worry- hard as it is. 
The breast clinics will examine you and give you a mammogram. They will give you the results there and then of an initial diagnosis with a definitive one up to 10 days later. 
The smaller lump could be your lymph nodes. 
let us know how you get on. 

Hi nice to meet you. I have also recently found a lump under my armpit. Is it painful and red? And how big? 

Hiya [@HappyBunny05]‍ 

theres no pain or redness 

the breast lump i estimate 2cm 

the lump in my armpit is a lot smaller (it was the GP that found it when carrying out her examination I'd not noticed it ) 

just over thinking everything at the moment

It is scary but you are doing the right thing to get it checked quickly. Most lumps are not cancer but even when they do turn out to be cancer, the sooner they are treated the better your chances and the less treatment needed. It is awfully scary I know as I went through this 5 years ago. It was cancer, they dealt with it quickly and efficiently and although it was a scary journey I am now fit and well.
