[|Human|] Hi. A lump suddenly appeared under my left breast. It was the size of a pea but it grew overnight and is quite sore and itchy. I also have felt very sleepy recently and have had a hard time getting over an illness. I have an appointment tomorrow but do malignant tumor typically hurt and itch?
