What risk factors contribute to esophageal cancer?
Tobacco and alcohol consumption are the major risk factors, especially for squamous cell carcinoma. Smoking and alcohol abuse each increase the risk of squamous cell carcinoma by five-fold. The effects of the two are.
Can a tanning bed cause skin cancer?
Yes, tanning beds can cause skin cancer. There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma. Using tanning beds increases your chances of getting each type. The Skin Cancer Foundation's website is a great resource for information about skin cancer.
Where can I find treatments for renal cell carcinoma?
Typical treatments for renal cell carcinoma include surgery, radiation or arterial embolization. There are also a variety of clinical trials available. More information regarding each of these treatments can be obtained from your physician or utilizing an internet directory such as WebMD.
What starts the skin cancer?
Skin cancer typically starts when the DNA of skin cells becomes damaged, often by exposure to ultraviolet (UV) radiation from sunlight or tanning beds. This damage can trigger mutations or changes in the DNA that cause the skin cells to grow out of control and form a cancerous tumor. There are three main types of skin cancer, each associated with different types of skin cells: Basal cell carcinoma (BCC): This type of skin cancer usually develops in the basal cells, which are located in the lower part of the epidermis (the outer layer of the skin). Basal cell carcinoma is often caused by cumulative exposure to UV radiation over time. Squamous cell carcinoma (SCC): Squamous cell carcinoma typically arises in the squamous cells, which are found in the upper layers of the epidermis. Like basal cell carcinoma, squamous cell carcinoma is often linked to prolonged exposure to UV radiation. Melanoma: Melanoma originates in the melanocytes, the pigment-producing cells in the skin. While UV radiation exposure is a significant risk factor for melanoma, other factors such as genetic predisposition and a history of severe sunburns can also contribute to its development. UV radiation from the sun can directly damage the DNA in skin cells, leading to mutations that disrupt normal cell growth and division. Additionally, UV radiation can suppress the immune system's ability to recognize and destroy abnormal cells, further increasing the risk of skin cancer development. It's important to note that while UV radiation is a primary risk factor for skin cancer, other factors such as genetics, immune suppression, exposure to certain chemicals, and a history of skin cancer or precancerous lesions can also influence an individual's risk. Protecting the skin from excessive sun exposure, avoiding tanning beds, and regularly checking the skin for changes are important steps in preventing and detecting skin cancer early.
What is squamous cell?
Squamous cells are a type of epithelial cell. Epithelial cells are cells that line the surface of an opening. For example skin cells are epithelial because they line the opening of the skin to the outside air. The lining of blood vessels are squamous as well, because they line the surface of the blood vessels. The basic types of epithelial cells are squamous, cuboidal, columnar, and transitional. The description can become more detailed such as stratified squamous and pseudostratified columnar. Squamous cells are very thin, flat cells. An example of squamous cells stacked on top of each other (stratified squamous) would be the outer layer of your skin. In fact these squamous cells are kertatinized and contain no active nucleus, and function mainly as a barrier to your inner body.
What is the survival rate for people who have basal cell carcinoma?
The survival rate of any illnesses or cancers is best discussed with your own doctor or oncologist since each patient has a unique set of circumstances and it cannot be given a general overall answer.
Different types of skin cancer?
Skin cancer is a condition that develops as a result of prolonged exposure to ultraviolet light. This prolonged exposure then causes the skin cells to grow in a rapid, out of control way ultimately leading to the formation of a cancerous tumour on the skin. Approximately 60,000 people in the UK develop this condition each year. However, what many people do not know is that not all skin cancers are the same. There are actually three different types; Basal Cell Carcinoma, Squamous Cell Carcinoma and Malignant Melanoma. In this article article I will be discussing these three in greater detail.1) BASAL CELL CARCINOMA (BCC):- This is the most common form of skin cancer and accounts for 75% of all diagnoses. As the name suggests it begins when the process of cell division goes wrong in the basal cells of the epidermis (the outer layer of the skin) and a cancerous tumour forms. This tumour often looks like a red ulcer on the skin which may bleed, crust or itch and is often given the nickname 'rodent ulcer'. Basal cell carcinoma typically appears on areas of the body that are exposed to the sun such as the arms, legs and face. Although it is the most common type of skin carcinoma it rarely kills. However, it can disfigure the skin if left untreated for a long period.2) SQUAMOUS CELL CARCINOMA:- This type of skin cancer accounts for between 15% and 20% of skin cancers. It begins when the squamous cells of the epidermis start to grow in a rapid and uncontrollable way which ultimately leads to the development of a cancerous tumour. This tumour often resembles a hard red lump or a flat, scaly, scab like area. Like BCC, squamous cell carcinoma often appears on parts of the body that are exposed to the sun and rarely kills. However, if left untreated it can spread to other areas of the body.3) MALIGNANT MELANOMA:- This type of skin cancer represents less than 10% of diagnoses. It develops in melanin producing skin cells called melanocytes. Malignant melanoma begins when the process of cell division goes wrong in these melanocytes and they start to divide and multiply uncontrollably leading to the development of a tumour. This tumour has a large, brown mole like appearance and can appear on your arms, back, leg or face. Although it resembles a mole there are subtle differences, Malignant melanomas are often a different colour to normal moles and they are often larger and more uneven. Unlike BCC and SCC, this type of cancer is very dangerous if not treated quickly and accounts for the majority of skin cancer fatalities.I hope this article has given you an insight in to this type of cancer. Whilst skin blemishes and odd looking moles may be non-cancerous they are a cause for concern. If you notice anything suspicious on your skin which does not disappear within a month then you should go see your doctor immediately. Early detection is a key element in the successful treatment of skin cancer and so it is far better to take the time and get yourself tested.Whilst every intention has been made to make this article accurate and informative, it is intended for general information only. Skin cancer is a very serious, life threatening condition and you should discuss any concerns, treatments or lifestyle changes fully with your doctor.Info from http://ezinearticles.com/?3-Types-of-Skin-Cancer-Explained&id=2101672
