What Could The Breast Lump With Tenderness, Redness And Stinging Be?

Hi I am a 48 yo female and I found a lump in my breast about 30 days ago. It started out the size of a pea, was very hard round and didnt move . now, 30 days later, it has become the size of a large grape and is not round any more but more flattened out altho still visible abouve the skin. It has also become very tender to the touch and red with sometimes a stinging sensation. I have had novasure ablasion so I dont have periods anymore. also... I live in Europe and connot get an appointment with the specialist until 2 months from now so I think im driving myself insane.... can you tell me anything that might ease my fears?

Thanks,
Tami
