Squamous  Cell Carcinoma Symptoms   

Squamous cell carcinoma tends to manifested, firstly, by flat reddish patches with a scaly brownish contour. When you scratch the lesion, it tends to bleed. Later, a growing bump that may have a rough, scaly surface can be formed. The parts of the skin most often affected by the tumor are sun-exposed areas: upper lip, scalp, external ear, back of hands and forearms, the ends of the feet and genitals. 

In general, the appearance of the tumor is more or less rounded, regular or bumpy. Sometimes, the tumor is ulcerated. White-yellowish appearance can also develop on the edges.
