Skin Cancer - Types, Risks, Symptoms And Treatment
Obviously, the topmost layers of the skin are the first to be affected; the three major types of skin cancer, basal cell carcinoma (rodent ulcer), squamous cell carcinoma and melanoma, all develop in the upper layer of the skin known as the epidermis. Basal cell carcinoma, the most frequent of the three, causes local erosions of tissue if neglected, while squamous cell carcinoma may spread if untreated. Fortunately, both these types can be successfully treated in nearly all cases. Squamous cell carcinoma sometimes occurs on the vulva in women after menopause and may be more difficult to deal with.
Melanoma, the least common of the three, occurs more frequently in sunny countries. Although a certain amount of sun on the skin is beneficial because it forms vitamin D, too much is dangerous. The danger has increased now that high levels of ultraviolet A radiation are reaching the earth's surface from the sun due to depletion of the ozone layer by flurocarbon chemicals from widespread use of spray cans. Melanomas are the most serious of the three skin cancers, once it starts to grow, it can spread rapidly. If detected and treated early enough, melanomas may be cured in about 75 per cent of cases.
The lighter your skin and eye colour, the more easily you will sunburn and the more likely you are to develop skin cancer. This likelihood increases with exposure to sunlight over both short periods - sunbathing on the beach to a point of, say, blistering - and long periods - pursuing an occupation, such as farming, in which many activities take place outdoors. Even moderate sunbathing after summer increases the odds that you will get skin cancer. The damage to the cells accumulates over time, so that people in their middle or later years are more likely to develop the disease.
The simplest way to avoid skin cancer is to reduce the exposure of you skin to the sun's cancer causing rays. Protect you skin by limiting your time in the sun and wear full clothing, those parts of the skin that are still exposed apply a good quality sunscreen to. The chemical composition of sunscreens block most of the sun's harmful rays.
Basal and squamous cell cancers have similar symptoms, while melanomas have their own special set of warning signs. What all skin cancers have in common, however, is change. That is what you should be on the lookout for. Basal and squamous cell cancers may start out small, rough patches of skin that are redder or paler that the surrounding skin. They can also start as tiny lumps or as small sores that bleed easily and seem to heal very slowly or not at all. If left untreated these tiny spots will soon grow and spread to surrounding tissue. Melanoma usually indicates its presence by altering the colour or appearance of a mole. Since melanoma involves cells that produce brown or black pigments, you should be aware of changes in dark spots or patches or moles and be on the lookout for new moles, moles that bleed, or any dark spot, new or old that changes colour, shape or size. Melanomas can be cured if treated in its early stage; those that go untreated may spread to other parts of the body, where they may attack vital organs.
Since skin cancer grows on the surface of the body, the first step in diagnosing them involves visual examination by a dermatologist. An experienced dermatologist can often determine whether a growth on the skin is or is not cancerous just by looking at it. If he suspects skin cancer he will remove a small sample and send it to a laboratory for examination under a microscope. There a pathologist will determine if the cells are skin cancer forming cells. If the samples reveal skin cancer, the dermatologist will remove the growth in one of a number of ways. Certain pre-cancerous skin problems may be treated by the application of a skin lotion containing anticancer drugs. In the case of basal or squamous cell cancer at an early stage, doctors remove the growth either surgically with a knife or by freezing it with liquid nitrogen. Melanomas, which are potentially more dangerous, are nearly always removed surgically together with surrounding tissue. Remember if the melanoma spreads to other parts of the body, other kinds of treatment such as chemotherapy - may be required. Radiotherapy, unfortunately, does not seem to be effective in treating melanoma. The key to treat this type of skin cancer is early detection.

Finding a Skin Cancer Specialist Near You
Whether you have a mole or some other markings on your body that are unusual, you need to take the time to go to your primary care doctor to get it checked out. Your doctor may biopsy it, and depending on the results, may decide to send you to a skin cancer specialist. This may be a dermatologist. Before going to the specific specialist, you should make sure that your insurance covers the issue. Make sure that the doctor has a good reputation, and make sure that he or she has a history of good results.
If you are going through your primary care physician, then you should probably go with the doctor that he or she chooses. It will make things easier with insurance referrals, and you will likely get in quicker to be treated. If, after you go to see someone, you find that you cannot deal with him or her, then you should look for someone else that your insurance covers. You will want to decide this before deciding to have the specialist do any major procedures.
A good reputation is something else to take into consideration. Doctors' reputations often go before them, but you should still look up reviews in various places. You can find them online. You can also talk to your primary doctor about a few options when it comes to choosing a skin cancer specialist. He or she should be willing to tell you what options might be best for you. If you know others who have had an issue like yours, then you could also speak with them.
The results of a certain physician's procedures should also be considered. You could ask for before-and-after photos if your issue is one for which the doctor might have pictures. You could also ask for statistics concerning the procedure.
Melanoma is actually a very serious form of cancer, and it is important to have it addressed quickly so that it does not metastasize. This outer covering on your body is the largest organ that you have, and it is connected to every other part of your body. Taking care of it is important.
After considering the various areas and meeting with a skin cancer specialist that your doctor has suggested, you should have a good idea of the direction you would like to go. You will either choose to stay with the one to whom you were referred, or you might ask for a different referral. What is important in this situation is that you take care of things quickly.

What is Cancer - Incidence, Diagnosis, Causation, Symptoms, Treatment and Prognosis
Cancer is second only to cardiovascular disease as the leading cause of death in the Western world. Although Cancer is primarily a disease of the elderly with more than 60% of deaths from cancer occurring in those over the age of 65, cancer can strike even the youngest of children.
Cancer appears to occur when the growth of cells in the body is out of control and cells divide too rapidly. Cancer can develop in almost any organ or tissue, such as the lung, colon, breast, skin, bones, or nerve tissue.
Most common sites are:
Prostrate 24%
Breast 13%
Lung 13%
Colon and Rectum 9%
Bladder 3%
Uterus 2.5%
The cause of Cancer is believed to be a combination of genetic factors and outside carcinogens such as tobacco, viruses, infection, asbestos, vinyl chloride, inappropriate diet.
Cancer often has no specific symptoms, so it is important that you limit your risk factors and undergo appropriate cancer screening. The signs and symptoms will depend on where the cancer is, the size of the cancer, and how much it affects the nearby organs or structures.
If a cancer spreads (metastasizes), then symptoms may appear in different parts of the body. As a cancer grows, it begins to push on nearby organs, blood vessels, and nerves. If the cancer is in a critical area, such as certain parts of the brain, even the smallest tumor can cause early symptoms.
But sometimes cancers start in places where it does not cause any symptoms until the cancer has grown quite large. Pancreatic cancers, for example, do not usually grow large enough to be felt from the outside of the body. By the time a pancreatic cancer causes these signs or symptoms, it has usually reached an advanced stage.
A cancer may also cause symptoms common to many other problems, such as; fever, fatigue and weight loss. This may be because the cancer uses up much of the body's energy or it may cause the release of substances which affect metabolism.
Some lung cancers make hormone-like substances that affect blood calcium levels, affecting nerves and muscles and causing weakness and dizziness.
It is important to know what some of the general (non-specific) signs and symptoms of cancer are, but remember that having any of these does not mean that you have cancer.
Most cancers can be treated and some cured, depending on the specific type, location, and stage. The earlier the cancer is found, the better the prognosis.
A good example of the importance of finding cancer early is melanoma skin cancer. Skin cancer can be easy to remove if it has not grown deep into the skin, and the 5-year survival rate (percentage of people living at least 5 years after diagnosis) at this stage is nearly 100%.
Screening for breast cancer with mammograms has been shown to reduce the average stage of diagnosis of breast cancer in a population. Colorectal cancer can be detected through fecal occult blood testing and colonoscopy, which reduces both colon cancer incidence and mortality, presumably through the detection and removal of pre-malignant polyps. Similarly, cervical cytology testing (using the Pap smear) leads to the identification and excision of precancerous lesions.
Testicular self-examination is recommended for men beginning at the age of 15 years to detect testicular cancer.
SIGNS and SYMPTOMS
Pain may be an early symptom with some cancers such as bone cancers or testicular cancer.
Long-term constipation, diarrhea, or a change in the size of the stool may be a sign of colon cancer.
Pain with urination, blood in the urine, or a change in bladder function (such as more frequent or less frequent urination) could be related to bladder or prostate cancer.
Skin cancers may bleed and look like sores that do not heal.
A long-lasting sore in the mouth could be an oral cancer and should be dealt with right away, especially in patients who smoke, chew tobacco, or frequently drink alcohol.
Sores on the penis or vagina may either be signs of infection or an early cancer, and should not be overlooked.
Unusual bleeding can happen in either early or advanced cancer.
Blood in the sputum (phlegm) may be a sign of lung cancer.
Blood in the stool (or a dark or black stool) could be a sign of colon or rectal cancer.
Blood in the urine may be a sign of bladder or kidney cancer.
A bloody discharge from the nipple may be a sign of breast cancer.
Many cancers can be felt through the skin, mostly in the breast, testicle, lymph nodes (glands), and the soft tissues of the body. A lump or thickening may be an early or late sign of cancer.
While they commonly have other causes, indigestion or swallowing problems may be a sign of cancer of the esophagus, stomach, or pharynx (throat).
A cough that does not go away may be a sign of lung cancer.
A cancer may be suspected for a variety of reasons, but the definitive diagnosis of most malignancies must be confirmed by histological examination of the cancerous cells by a pathologist.
TREATMENT
Once diagnosed, cancer is usually treated with a combination of surgery, chemotherapy and radiotherapy.
Radiation therapy may be used to treat almost every type of solid tumor, including cancers of the brain, breast, cervix, larynx, lung, pancreas, prostate, skin, stomach, uterus, or soft tissue sarcomas.
Most forms of chemotherapy target all rapidly dividing cells and are not specific for cancer cells, although some degree of specificity may come from the inability of many cancer cells to repair DNA damage, while normal cells generally can.
Contemporary methods for generating an immune response against tumours include intravesical BCG immunotherapy for superficial bladder cancer, and use of interferons and other cytokines to induce an immune response in renal cell carcinoma and melanoma patients.
Pain medication, such as morphine and oxycodone, and anti-emetics, drugs to suppress nausea and vomiting, are very commonly used in patients with cancer-related symptoms. transmission and disease.
Advances in cancer research have made a vaccine designed to prevent cancer available. The vaccine protects against four HPV types, which together cause 70% of cervical cancers and 90% of genital warts.
The consensus on diet and cancer is that obesity increases the risk of developing cancer. The cancer-fighting components of food are also proving to be more numerous and varied than previously understood, so patients are increasingly being advised to consume fresh, unprocessed fruits and vegetables for maximal health benefits.
