Types of skin cancer

Cancer is uncontrollable and rapid division of abnormal cells of body in any part, organ and tissue. It is spreading worldwide due to unhygienic environment. Our environment pollutes due to carcinogens. They bring about genetic mutations in our DNA. Normally body has enzyme and mechanisms to repair a damage in a gene, nucleotide or whole DNA. However, due to carcinogens, body lost its control over mutant genes. We all are well familiar with the function and importance of genes in DNA. It control all the activities in body. Cells containing mutant genes become abnormal and start to proliferate at fast rate. Our immune system try to fight against these cells. However, immune system may also damage in this fight.

Skin cancer

As its name indicate, it is the rapid growth of abnormal skin cells. They have ability to spread and invade neighboring cells.

Causes of skin cancer

The main cause of skin cancer is ultraviolet rays in sunlight. These are dangerous to skin. These are nonionizing rays. Ozone is an allotropic form of oxygen that is present in stratosphere about 25-30Km above earth. It filters dangerous rays and send them back. In this way, it prevent human from lethal effects of these rays. Due to human activities, ozone layer is becoming thinner and disable to filter rays. Chlorofluorocarbons is the main cause of ozone thinness. When rays make contact with skin, it cause mutations In DNA.

Types of skin cancer

Following are important types of skin cancer

  • Melanoma
  • Basal cell skin cancer (BCC)
  • Squamous cell skin cancer (SCC)
  • Merkel cell carcinoma
  • Keratoacanthoma
  • Kaposi’s sarcoma
  • Sebaceous carcinoma
  • Paget’s disease of the breast
  • Dermatofibrosarcoma protuberans
  • Leiomyosarcoma
  • Angiosarcoma

Basal cell carcinoma

It is present on body parts that mostly expose to sunlight like face, hands and feet. It is most common type of cancer. It appear like pearly translucency to fleshy color. Tiny blood vessels may appear on the skin surface. It can cause ulceration that is its characteristics feature. This type of cancer can rarely cause death. It can easily treated with surgery and chemotherapy.

Squamous cell skin cancer

It is less common than BCC. It is more dangerous than previous type because it can spread to other organs. Invading rate is greater in lip, ear and mouth cancer. It increases in immune deficient persons. Its cause is UVB ray that directly target the DNA and damage genetic messages in the form of gene.

Melanoma

Melanoma is also a common type of skin. It is less frequent than other two types. It may lead to death if it starts spreading. UV rays are its major cause that indirectly effect DNA.

These are some most important types of skin cancer that can effect a large number of population in any country. Poor hygienic conditions should remove from our environment. As we hear that precaution is better than cure. Similarly, care is better than treatment. We should end up the root causes of cancer. Its major cause is the lack of awareness in people of backward areas. Skin cancer not only lead to death, it can damage your beauty. Face skin cancer, lip cancer, hand and feet cancer greatly decrease the beauty of effected persons.
