Found a lump

hello, 

I found a lump in my left breast Tuesday morning in the shower, freaked out. My mum had a mastectomy when pregnant with me. She got us checked to see if it was hereditary but it came back negative. I think I believed that this makes me immune! What a prat. 

Called in work and set cover, and went to the dr. Emergency referral made and now waiting to attend appointment on Tuesday. 

Went straight back to work to keep mind occupied. Trying to run and eat healthily ... nothing else I can really do. I just seem certain it’s cancer. Since I found the lump I’m noticing every twinge, ache and pain. Was this there before Tuesday or am I imagining it? 

Letter from hospital said 2ww so now panicking and thinking my GP thinks it cancer. 

Will the appointment be painful? When will the result come? Should I head back to work? What if cancer is confirmed? 

I’ve been with my partner and father of my child for over 20 years, we met at school. He asked me to marry him and wedding is in three months. Everything just seems is turmoil.
