Introduction

This collection of cells does not spread to harm you and could be benign or malignant. During a medical treatment, the tumor and the tissue that surrounds it are removed surgically. Through a straightforward surgical procedure, many skin cancers can be removed quickly and easily. Frequently, no additional therapy is required. When the body fails to repair DNA damage in skin cells, allowing the cells to multiply and grow out of control, skin cancer develops. Skin type and genetics are just two of many factors that could lead to the death of skin cells. The amount of exposure to ultraviolet (UV) light from the sun to tanning beds increases the risk of developing skin cancer.

Description

For the majority of these procedures, local anaesthesia is used to numb the skin before surgery. They can be carried out in the offices of a dermatologist, a surgical oncologist, a general surgeon, a plastic surgeon, a nurse practitioner, or a physician assistant. Other operations are carried out in a hospital operating room under local or general anaesthesia, such as more extensive wide excisions and sentinel lymph node biopsies. This approach is widely used to treat Merkel cell carcinoma. Surgery is typically used to treat skin cancers. Patients with basal cell or squamous cell carcinomas may have an outpatient procedure with a local anaesthetic performed by a dermatologist or other qualified doctor [1].

In some cases, nonsurgical procedures may be used to get rid of or kill localised skin cancer cells. These techniques can be performed alone or in conjunction with other treatments to treat early-stage basal cell or squamous cell carcinomas, as well as noncancerous or precancerous lesions. The following are some illustrations of topical treatments. This process combines photosensitive medication with light to destroy cancer cells. In this method, a light-sensitive chemical, often aminolevulinic acid, is applied directly to the tumour. The medicine is activated and targets skin cancer cells for up to 18 hours when the treated area is exposed to a specific blue light [2]. The only test required to assess the stage of superficial skin malignancies like basal cell carcinoma, which seldom spread, is a biopsy that eliminates the entire tumour. However, if you have a big squamous cell carcinoma, Merkel cell carcinoma, or melanoma, your doctor might advise additional testing to find out how far advanced the cancer is. Additional tests could involve surgically removing a neighbouring lymph node and testing it for malignancy or imaging tests to look for cancer in the nearby lymph nodes (sentinel lymph node biopsy) [3].

The most prevalent malignant condition, especially in Caucasians, is skin cancer. Each year, more than a million new cases are reported globally. The cells from whence they arise and their clinical characteristics are used to name the various forms of skin cancer. The most prevalent varieties are malignant melanoma, basal cell carcinoma (BCC), and squamous cell carcinoma (SCC), collectively known as nonmelanocytic skin malignancies (NMSC). Skin cancer patients exhibit the normal indications of chronic sun damage, such as collagenosis, uneven pigmentation, skin wrinkles, telangiectasia, and solar keratosis on sun-exposed areas. The most exposed parts of the superficial BCC have tiny ulcerations and have a red, slightly wrinkled, scaled appearance. They might have a poorly defined border and be formed either circular or oval. The fibrosis in the centre may be uniform. Clinically, a superficial BCC may present as subacute or chronic dermatitis [4].

Risk factors for MM and NMSC include skin type and UV exposure. Cancer-causing UVA and UVB can come from either natural or manmade sources. The UV rays have a carcinogenic effect and suppress the immune system in addition to producing the desired tanning and vitamin D. The socalled intermittent sun exposure, together with childhood and adolescent solar exposure, is the main risk factor. A chronic or professional exposure is a weaker risk factor, with the exception of head and neck MM. Numerous freshly produced naevi, sunburns, and the presence of actinic keratosis are statistically associated to a higher risk for this type of cancer. Other risk factors are also connected to UV exposure [5].

Conclusion

The initial steps in diagnosing skin cancer include a dermatological examination, medical history, dermoscopy, surgical biopsy, and pathohistological biopsy. Using a lens (or lens system) and a powerful light source, dermoscopy is a noninvasive method that differentiates between typical skin cancer changes. In both MM and NMSC, a pathohistological examination and a skin biopsy are used to confirm a suspect lesion's diagnosis. The biopsy, which involves the removal of 2 to 5 millimeters of healthy skin, can be carried out with either a punch biopsy or a shave biopsy. Additional treatment is chosen based on the size and location of the tumor in relation to anatomy.
