On my first week I had a red patch near my nipple in left chest with a liquid filled weird thing, was small but it?s kind of a big long and just bigger then after 3 days it was reduced and after that I had throat pain in middle and down throat, so after that it was okay but swollen left neck is present with swollen lymph nodes and gland on left chest. Sometimes chest and nipple area heats or make a burn effect. Swollen lymph node can be felt on back of neck. Is it cancer or can be something else too?
