Doesn't skin cancer hurt or itch?

Does skin cancer cause no pain or itching? What are the symptoms? Skin cancer is a malignant tumor that is very common in white people. Skin cancer is rare in my country and ranks 11th among all malignant tumors in the body. Because people rarely pay attention to it, even though skin cancer grows on exposed skin, the early diagnosis rate of skin cancer is still very low.

What are the early symptoms of skin cancer? The skin of the elderly may have some precancerous manifestations, among which senile keratoma and leukoplakia are the most common. There are also some chronic skin diseases, such as keloids after burns or trauma, chronic ulcers that do not heal for many years, chronic dermatitis, senile skin warts, chronic fistulas or sinus tracts, radiation ulcers, etc. If these lesions increase in size, or ulcerate, harden, thicken, deepen pigmentation, hyperkeratosis, and even bleed after regular treatment, you should be alert to the possibility of skin cancer.
What are the early symptoms of skin cancer? In short, if painless nodules with hard texture and raised edges appear on the skin of the elderly and do not heal after long-term treatment, they should be checked at a regular dermatology hospital to rule out the possibility of skin cancer.
