skin cancer doesn't arise from the stratum corneum because that layer of the epidermis is composed mainly of dead cells that do not have a blood supply for cancer cells to use.
Foremost the Stratum Corneum is the top layer of the Epidermis, a cutaneous membrane. It is to be noted that the Stratum Corneum consists of 25-30 layers of non-dividing or dead cells. Therefore this environment does not accomodate the malignant cancer cells that depend on a living healthy area in which to chronically divide.
a. Basal cell carcinoma arises in the basal cell layer of the epidermis. b. Malignant melanoma arises from melanocytes located in the basal layer of the epidermis. c. Squamous cell carcinoma arises in the squamous cells of the epidermis, which are found in the upper layers of the epidermis.
Malignant melanoma arises in the Stratum basale layer of the epidermal layer.
Stratum Basale. The cells in the Stratum Spinosum are spiny shaped and are called prickle cells. These arise during tissue preparation when the cells shrink.
Cancer can arise anywhere in the human body!
Kidney, or renal, cancer occurs in the kidneys. It can develop from a tumor or it can spread there from another part of the body.
Yes. Carcinoma is defined as cancer that arise from epithelium. So nasopharyngeal carcinoma is cancer that may appear at any site in nasopharynx.
No, not necessarily. it might arise as an independent one as well as secondary to some other malignant neoplasm.
Because too many people stopped wearing sunscreen.
The major skin area from which the derivatives arise is the stratum basale, which is the deepest layer of the epidermis. This layer contains stem cells that continuously divide and differentiate to give rise to the various cell types in the epidermis, including keratinocytes, melanocytes, and Merkel cells. These cells migrate upwards through the layers of the epidermis to replenish and repair the skin.
Adenoid cystic carcinoma is a rare slow growing cancer. It is considered a head and neck cancer but can arise in other areas of the body. There are limited treatments for it because it is so rare. The most common areas of the body for it to metastasize to is the lung, liver and bone.
No. Mouth cancer is often the result of a chronic habit/addiction, such as chewing tobacco or smoking a pipe (although some mouth cancers arise spontaneously). Cancers, however, are not communicable from person to person.
Will arise (for example, I will arise).
