Skin cancer can cause systemic allergies

Improper treatment of any disease will cause a series of complications, and skin cancer is no exception. Therefore, patients also need to have a corresponding understanding of the complications of skin cancer so that they can take corresponding preventive measures during treatment. So can skin cancer cause systemic allergies? What diseases can this disease cause?

The following are some of the complications that skin cancer can cause:
1. Nodular ulcer: At first, some small waxy nodules ranging in size from millet grains to peas will appear on the skin surface. The epidermis will be loose and accompanied by a small number of continuously enlarged capillaries protruding from the skin surface. Some will also have erythema without protrusion, while others will appear nodular (i.e. pimples), and the skin on the surface will slightly sink downwards.
2. Pigment: The nodules are shallower and the damage is the same as the nodular ulcer type. Because it contains more pigment, the edge of the damage has a pearly luster, and there are dot-shaped or reticular dark brown or black brown pigment spots. Some pigmentation can also be seen in the center. After the scab is formed, it is easy to bleed when the scab is removed. The scab may be dark brown or even carbon black granules, which is similar to malignant melanoma and is easy to misdiagnose.
