The skin is the largest organ in the body and it protects all of our internal structures such as other organs (e.g. the heart) and glands. The main function of the skin is to be a first line of defense for the body. It protects the body from harmful UV rays that are emitted from the sun and it also helps to regulate body temperature. For example, if it gets to hot outside the skin will cool the body by secreting perspiration. Plus it helps us to sense our surroundings through the many nerves located on its surface. Like all other organs the skin is susceptible to things that may harm it such as skin cancer, cannibalism, psoriasis, seborrhea, and Toxic Epidermal Necrolysis . ...view middle of the document...
Melanoma ranges in the skin.
Basal cell carcinoma is the second most common form of skin cancer. The major cause is radiation from the sun and from tanning. It happens when radiation goes deep into the layers of the skin and penetrates the basal layer of the epidermis. This layer is the part that forms new skin cells. When the DNA in the cells is mutated, and instead of going through the normal skin cell life cycle, it keeps growing and growing. It isn’t likely to spread to other parts of the body, but if it isn’t treated, it can spread to the bones. Another cause of basal cell carcinoma is improper/ infected tattooing. Because tattoos are permanent, the ink needs to be injected into the basal cell layer. If something goes wrong, there could be a risk for cancer.
Basal cell carcinoma that is on the nose
• Squamous cell carcinoma forms in the squamous layer of the epidermis and the mucous membranes. It can be caused by radiation, burn damage, or injuries. Like all skin cancers, squamous cell carcinoma starts to happen when DNA in the skin cells is damaged and they don’t continue in the normal life cycle. They continue to grow and they don’t stop.
What can you do to avoid skin cancer?
What anyone can do to avoid skin cancer is to avoid radiation from sunlight when it is most dangerous. Do not spend too much time outside during the hottest hours of the day, which are from 4 p.m. to 6 p.m.
What Are The Most Common Treatments for Skin Cancer?
Skin cancer has many different treatments especially depending on what type of skin cancer is occurring. Chemotherapy, radiotherapy, surgery, immunotherapy, and photodynamic therapy (PDT) are all different treatment methods for skin cancer.
• Chemotherapy is type of treatment that uses drugs to destroy tumors (it can be used for skin cancers). Chemotherapy can be taken by the mouth or injected into the blood stream where it can reach the cancerous cells throughout the body. When chemotherapy is done to an area such as an organ, cerebrospinal fluid, or a body cavity, the drugs for the most part tend to affect the cancer cells. Retinoid is an example of a chemotherapy drug that treats squamous cell carcinoma.
Drugs are used to help a person fight cancer in chemotherapy.
• Radiation therapy uses x-rays, gamma-rays, and other charged particles to shrink and kill cancer cells by damaging the DNA of those cells. The radiation can be delivered through an external beam (to the external part of the body) or from an internal radiation beam which is placed in the body, near the cancerous cells. There is even a type of radiation therapy where the health professional can place an iodine substance that can travel through the blood to annihilate the cancerous cells.
Radiation Therapy uses x-rays, gamma rays, and other charged particles to heal tumors.
• Cancerous cells can also be taken out through surgeries such as excisions, where professionals use a surgical knife to remove the...
