Squamous cell neoplasms refer to a group of abnormal tissue growths that occur in the squamous cells, which are thin, flat cells that make up the surface of the skin, lining of certain organs, and the respiratory and digestive tracts. These neoplasms are characterized by the uncontrolled replication and accumulation of squamous cells, leading to the formation of tumors or lesions.
These abnormal growths can be benign (non-cancerous) or malignant (cancerous), with squamous cell carcinoma being the most common malignant form. Squamous cell carcinoma is a type of skin cancer that typically develops on sun-exposed areas such as the face, scalp, ears, neck, hands, or lips. It can also arise in other parts of the body, including the bladder, cervix, esophagus, lung, and anus.
Risk factors for squamous cell neoplasms include excessive sun exposure, exposure to certain chemicals or toxins, human papillomavirus (HPV) infection, a weakened immune system, and certain genetic conditions.
Symptoms of squamous cell neoplasms can vary depending on the location and extent of the growths but may include the development of rough, scaly, or crusty patches of skin, persistent sores that do not heal, changes in the appearance of existing moles or warts, or the presence of lumps or nodules.
Early detection and treatment of squamous cell neoplasms are crucial for better outcomes. Treatment options may include surgical removal of the growths, chemotherapy, radiation therapy, targeted therapy, or immunotherapy, depending on the stage and location of the neoplasms.
