Squamous cell carcinoma (SCC) is a type of cancer that affects one of the three types of cells found in the epidermis, the outermost layer of the skin. These cells, known as squamous cells, are located near the surface of the skin and are constantly being shed as new cells are formed. However, when the DNA of these cells undergoes abnormal changes due to factors such as excessive exposure to sunlight, genetics, or other harmful agents, it can lead to the development of cancer.
Fortunately, most cases of SCC can be successfully treated, especially when diagnosed in the early stages. However, if left untreated, SCC lesions can become disfiguring or even invasive, spreading to other parts of the body. This is why it is crucial for individuals to consult a dermatologist or general physician if they notice any suspicious skin discolorations or growths. Early detection is key to preventing the cancer from spreading and increasing the chances of successful treatment.
Recognizing the Appearance of Squamous Cell Carcinoma
Identifying the presence of squamous cell carcinoma involves observing specific visual characteristics. Early signs often manifest as dome-shaped bumps that slightly protrude from the skin or as scaly, reddish patches. It is worth noting that these patches tend to bleed easily when scraped or picked. Moreover, larger squamous cell carcinomas may cause itching and pain when scratched. In some instances, these bumps can emerge through existing scars or sores, indicating a potential case of squamous cell carcinoma. It is essential to notify a dermatologist of any changes observed in these skin markings. While squamous cell carcinoma typically develops on sun-exposed areas such as the face or scalp, it can also occur anywhere on the body.
Diagnosis of Squamous Cell Carcinoma
When it comes to diagnosing Squamous Cell Carcinoma (SCC), dermatologists play a crucial role. They conduct thorough examinations to assess the color, shape, texture, and size of the suspected SCCs. In cases where a malignant growth is suspected, dermatologists may opt for skin biopsies. This procedure involves the removal of a small tissue sample, which is then sent to a laboratory for further testing.
Dermatologists may also employ a dermatoscope during examinations to obtain a closer inspection of the lesion. However, in some instances, more advanced SCCs can be identified without the need for a biopsy.
