Bleeding
An ulcerative carcinoma of the lips usually bleeds, as it happens with any other malignant tumor with ulceration. Bleeding from carcinoma of the tongue is a late feature of the disease. Melanomas can also ulcerate and bleed in late stages. Late stage of cancer is also associated with an increase in vascularity of the tumor, which predisposes to easy bleeding in response to small traumas.
Foul-smelling discharge
Carcinoma of the lip in late stages can have fungating and foul-smelling discharges which are thin, watery, blood-stained, and usually infected.
