The type of skin and skin cancer

Skin

The skin is the 1 F which overlays in the body surface jacket, is the initial weapon that we resist the external world, it can protect our body to be free from hot, the injury of the ray or germ infection;Make the human body be placed in constant temperature appearance, and store to save water, fat and vitamin D.A personal skin of whole body add can as heavy as 6 pound, can be treated as biggest organ of human body.The skin has 2 F:Externality layer with inside leather layer.

Epidermis layer mainly from be called the scale form of "scale form cell" cellular.Scale form the underneath of the cell is a circular cell and be called base cell.Externality most the bottom layer imply melanin cell, these cells will produce melanin, but very dye of how much can make the skin present a color of dissimilarity, this was the skin color that we say.

The leather layer includes blood vessel, lymphoid tube, hair bag and gland body.These gland physiques secrete sweat liquid and sebum.The sweat liquid can help to regulate body temperature, but the sebum can then prevent°from a skin dry.Sweat liquid and sebum are to eject a skin through a kind of thin bore which is called pore superficial.

What is a cancer?

The cancer is 100 various paroxysms to know together as.Although grow cancer each time each not same, they have a total, that is that they are the body cell occurrence pathological changeses formation.

That what is a cell pathological changes again?The healthy cell will have growth, abruption and death of regulation, old cell drive new the cell replace.But sometime, the growth of some cells and abruption meeting because of some complicated reason but out of control.They split up too quickly, became the organization of surplus.But this be"tumor" that we be so called.The tumor can be positive and be also likely to be malignant.

Benign tumor:
Benign tumor wasn't a cancer, it is can pass surgical operation excision.The cell of benign tumor will not transfer other organs of body.Usually under the circumstance, the benign tumor will not relapse after cut off.The most important BE, the benign tumor will not constitute to the life dangerous.

Malignant tumor:
The malignant tumor is the cancer that we be so called.Usually under the circumstance, the malignant tumor is more serious and the end even will threaten our lifes.The cancer cell will continuously infringe upon, deformation the organization or organ of the periphery.More serious BE, the cancer cell will escape from the restriction of tumor and get into blood or lymphoid system.This be the cancer cell from deliver cancer proliferation at first, the process in other part formations new tumor.This process calls transfer of cancer cell.

The type of skin cancer:

The most familiar of two kinds of skin cancers be cancer and the scale form cell cancer of the base cell.The base cell cancer has the most parts of skin cancer total amount.This kind of cancer growth is very slow-moving, generally will not spread to other organs of body.The scale form cell cancer also seldom spreads, but the possibility of its proliferation want to compare base cell a cancer to want greatly. The skin cancer has to as early as possible diagnose and cure, because they will invade and break peripheral organization.

Cancer and the scale form cell cancer of the base cell sometimes also are called the lump skin cancer of the non- melanin.Another cancer of skin is a melanin lump.This kind of cancer starts hair in melanin cell.
