Squamous epithelial cell carcinoma of the skin diagnosis
Any persistent changes in the skin should be brought to your doctor's attention. They will then conduct a physical examination of the suspected tissue area. To get a definitive diagnosis, this suspicious tissue must be examined under a microscope, a process known as a biopsy.
There are different types of biopsies to diagnose skin cancer. Doctors recommend specific surgical procedures based on the size, shape and location of the tumor. Patients usually have a local anesthetic before surgery, and the wound may be sutured after surgery.
Types of skin cancer biopsies
Local excision/excision biopsy: All or part of the suspect area is removed with a scalpel under local anesthesia. Depending on the size and location of the lesion, this type of biopsy can be performed in a doctor's office or in a hospital outpatient setting. If the growth is small enough to be completely removed during biopsy, local excision can be both a diagnostic procedure and a treatment.
Perforation biopsy: The doctor uses a special tool to Pierce the suspect area and remove a round, cylindrical piece of tissue. If necessary, the patient may receive stitches to close the wound.
Shaving biopsy: The doctor scraped away a piece of tumor. This can be done with a scalpel, surgical scissors, or other special tools. Usually no stitches are needed.
Biopsy result
After the biopsy procedure, the skin sample is sent to a pathologist - a doctor who specializes in diagnosing diseases. After examining the tissue under a microscope, a pathologist will make a diagnosis.
Abnormal results include benign (non-cancerous) growths such as moles, warts, and benign skin tumors. If the sample shows cancer, the pathologist will determine whether it is a basal cell carcinoma, squamous cell carcinoma, or melanoma.
Determine if your cancer has spread
Basal cell carcinoma usually stays in one site and does not spread. However, melanoma or squamous cell carcinoma in particular, which includes large areas of skin, may require additional testing to see if the cancer has spread (metastasized). Skin cancer may invade other layers of the skin or travel to surrounding nerves or lymph nodes. If the doctor suspects that the cancer has spread, the patient may undergo some medical imaging or a lymph node biopsy.
