Let me introduce to you the non-surgical treatment of skin cancer

Skin cancer treatments can be divided into surgical treatments and non-surgical treatments. Everyone needs to know more about this aspect. Next, let the experts discuss with everyone what non-surgical treatments for skin cancer are. I hope it can help everyone better understand non-surgical treatments for skin cancer .

1. Cryotherapy This type of skin cancer is a non-surgical treatment for skin cancer that is suitable for curettage and is also suitable for cryotherapy, especially for some cases rich in fiber components that are not conducive to curettage; cases that relapse after curettage and radiotherapy are more suitable for cryotherapy, but the lesions must be limited to the skin. Those that invade other tissues and organs are not suitable for cryotherapy. A biopsy must be performed before treatment because there is no specimen for pathological examination after cryotherapy. The surgeon marks the tumor boundary and uses the lesion and the surrounding 2-5mm normal tissue as the treatment area. -20℃ is the best temperature to ensure tumor cell lethality, and then begins to thaw. Slow thawing can kill tumor cells more effectively than rapid thawing. Rapid thawing is only used to prevent damage to more normal tissues. The advantage of cryotherapy is that it has a more beautiful wound than curettage, and its cure rate can reach 95% to 97%. For lesions in the eye area, this method can still be used as long as the eyeball is covered with a hot protective material. However, this method is used to treat scalp cancer because the recurrence rate after surgery is high, so it is generally considered not to be used.

2. Chemical Surgery This method was first invented by American doctor Mohs. After fixing the tumor with zinc chloride paste, it is cut horizontally and sent for pathological examination until there is no cancer at the base of the cutting edge. However, nowadays, the step of fixing the tissue with zinc chloride paste has been omitted. Fresh tissue is cut horizontally directly and sent for pathological examination continuously until there is no cancer at the base of the cutting edge. This method is suitable for cases with large lesions with unclear boundaries and recurrence after treatment. This is a non-surgical treatment method for skin cancer.

3. Laser treatment There are many types of lasers commonly used in dermatology, such as carbon dioxide laser, helium-neon laser, etc., and their uses are different. Carbon dioxide laser is mainly used in the treatment of skin cancer, and carbon dioxide laser can replace electrical drying. Carbon dioxide laser is an infrared beam that diverges at a wavelength of 10600nm. When the beam diverges, it can be used to vaporize skin tumors, such as basal cell carcinoma and superficial squamous cell carcinoma, making the skin tumor disappear. It can also be used in combination with curettage, which is also a non-surgical treatment for skin cancer.

4. Scraping treatment Skin scientists generally use scraping and electrodesiccation to treat basal cell carcinoma and superficial squamous cell carcinoma. It is performed by using the boundary between the tumor and the normal skin color around it. Scraping is performed with a scraper. Before the operation, attention should be paid to the appropriate size of the scraper, which is generally slightly larger than the neoplasm. During the operation, a little downward force is applied to avoid slipping. After routine disinfection, 1% procaine or lidocaine solution is injected into the base of basal cell carcinoma or squamous cell carcinoma to make it obviously bulge. After selecting a suitable scraper, a 3-4mm scraper is generally used to dig out the cancer lesion. A small scraper with a diameter of 1-2mm and a sharp edge is used to scrape the surrounding and base of the tumor bed to scrape away the residual cancer extending into the surrounding base normal tissue. Sometimes, because the normal dermis tissue is relatively solid, a slight gravel-like sound can be heard during scraping, while the tumor is crisp and silent. After scraping, an electrocautery is used to burn the surrounding and base of the tumor bed, and then the charred tissue is scraped off with a scraper. The wound is coated with antibiotic ointment. Its advantage is that it can obtain a smooth and beautiful wound with only a small amount of pigmentation. Its disadvantage is that there are no pathological examination results of the cutting edge, and it is impossible to know whether there is any cancer residue at the cutting edge. Therefore, this method should be used with caution.

Through the above introduction, everyone should have some understanding of the non-surgical treatment methods for skin cancer. I hope it can bring some help to everyone. I wish that patients can choose the treatment method that suits them as soon as possible and recover soon.
