There are various types of cancer that can affect the feet. The most common form of these is Squamous cell carcinoma, which can start as a small, itchy callus-like lesion. It’s often mistaken for a plantar wart, fungal infection or eczema. This type of cancer is usually limited to the skin, but it can advance and become more aggressive, invading other parts of the body.
Basal cell carcinoma is a different type of cancer that usually results from sun exposure. This type of cancer appears as small, pearly white bumps or oozing sores. Basal cell carcinoma rarely spreads beyond the skin.
Kaposi’s sarcoma begins with abnormal cell growth beneath the skin, leading to the appearance of dark, reddish lesions on the skin. These growths may range from painless or extremely painful.
Malignant melanoma is one of the most dangerous types of skin cancer, requiring early detection to ensure patient survival. This is because as they spread deeper, they can invade the body through the lymphatic system or blood vessels. Malignant melanomas can be found under a toenail, on the soles, or on top of the foot. They can be mistaken for common moles, which can fatally delay diagnosis and treatment.
In all cases, early detection is key to managing the risk of cancer, as pre-cancerous lesions can easily be removed to prevent their advancement.
