What Is Skin Cancer?
The term Skin Cancer refers to a condition marked by abnormal growth of the skin cells. Majority of the skin cancer cases occur in the skin areas that remain exposed to sunrays. However, skin cancer can also affect skin areas, which ordinarily do not get exposed to sun. Skin cancer can be of 3 major types: basal cell carcinomas, squamous cell carcinomas and melanomas. The less common skin cancer types include Kaposi sarcomas, Merkel cell carcinomas and sebaceous gland carcinomas. Let us now get acquainted with the symptoms of the above mentioned types of skin cancer:
Symptoms of basal cell carcinomas: This skin cancer type usually affects the sun-exposed body parts, for instance our face, scalp or ears. Basal cell carcinomas might appear in form of waxy or pearly bumps or a flat and flesh colored lesions or brown scars.
Symptoms of squamous cell carcinomas: Squamous cell carcinomas also occur in the sun-exposed body parts like hands, ears, lips and face. This form of skin cancer appears as firm, red nodules or flat lesion having crusted and scaly surfaces.
Symptoms of melanomas: Melanomas can affect all our body parts. Melanoma can occur in normal skin areas or in the existing moles. In men, the body parts that are most likely get melanomas include neck, head and trunk. The women, on the other hand, get melanoma symptoms in their lower legs. However, patients of both genders can develop melanoma in body parts that do not get exposed to sun. Melanoma can occur in individuals with all types of skin tones. Individuals with dark skin are likely to get the disease in their soles or palms or beneath their toenails or fingernails. The common signs of melanoma include:
- Large brownish spots having darker speckles
- Small lesions having irregular borders; some parts of these lesions appear white, red, blue-black or blue
- Moles changing in color, feel or size; bleeding moles also indicate occurrence of melanoma
- Dark lesions in the toes, fingertips, soles or palms of the patient
- Dark lesions in the mucous membranes forming the lining of our anus, vagina, nose or mouth
Symptoms of Kaposi sarcomas: This skin cancer type affects the blood vessels of our skin. The condition is indicated with formation of purple or red patches in our mucous membranes or skin.
Symptoms of Merkel cell carcinomas: This skin cancer type results in formation of firm and shiny nodules either underneath or over the surface of our skin. The nodules might also appear on our hair follicles. Merkel cell carcinomas occur in sun-exposed body parts like legs, arms, neck and head.
Sebaceous gland carcinomas: It is a skin cancer type beginning from our sebaceous glands or oil glands. The symptoms include hard and painless nodules. The most common body part affected by this form of skin cancer is our eyelids; however, sebaceous gland carcinomas can also affect other body parts.
Latest on Skin Cancer
The latest on skin cancer is that the risk of developing skin cancer from tanning beds is now two times more than spending time in the hot sun of the Mediterranean. This is a discovery that a new study conducted by a team in the University of Dundee in Scotland found out. The scientists actually examined 400 tanning beds in the United Kingdom. The scientists then measured the ultraviolet levels of radiation. The UV radiation was emitted at levels that are beyond the guidelines provided in United Kingdom.
The average power of the tanning bed too was actually double the prescribed limit. Thus, the risk of getting skin cancer by using these beds was also given a consideration and then the quote was compared with the risks that the Mediterranean sun poses after bedtime.
The team discovered that [...]
All about Telangiectasias
Telangiectasias are small blood vessels that are dilated near the surface area of the skin with mucous membranes, that have a diameter of around 0.5 ml to 1 ml. These are seen to develop in any part of the body but are more common on the face and the chin, cheeks and the nose. These are also seen to develop on the legs especially on the area of the upper thigh, and also below the knee joint. Sometimes they are found around the ankles too.
There are some kinds of telangiectasia that are developed due to the abnormalities that are very similar to the way the benign vascular neoplasm's behave. These are composed of groups of capillaries, arterioles, and also venules. The telangiectasias are lesions of vascular nature and they normally blanch when they are tested with diascopy.
The causes [...]
Skin Cancer and Tanning Beds
A group of scientists working at Yale School of Public Health, an organization of New Haven of Connecticut has found that the young individuals using tanning beds have 69% higher risk of suffering from basal cell carcinomas or BCC early in their life than the ones who do not use any such tool. The study’s senior author, Susan Mayne explains that during their study on skin cancer they found that indoor tanning is the most common factor among young patients diagnosed with the disease. She also mentioned that this effect of indoor tanning is more evident among women with as much as 70% of the early-onset BCC detected in females.
Finding of this study have supported a previous study conducted by researchers of University of Minnesota. The scientists of University of Minnesota found that individuals [...]
Melanoma Cancer Awareness Month – Important Facts & Advice You Should Know
Though melanoma cancer constitutes for merely around four to five percent of all cases of skin cancer, it is responsible for majority of the skin cancer linked mortalities but, detection & treatment in earlier staging often cures it.
Among males, melanoma is mostly discovered in the region in-between hip & shoulder or spotted on the neck & head areas. Among females, melanoma mostly arises on the lower leg areas.
Despite the likelihood of developing melanoma augments as one ages yet it’s one of the commonest cancers afflicting younger adult populaces.
Skin cancer afflicts 1 from 5 people in the U.S. & diagnosis of over a million novel cases annually. From them, over 65000 are melanoma-caused - a cancer form which claims almost 11000 lives yearly.

Get Naturally Tanned Minus Sun Exposure or Skin Cancer Risk
Finding a fake tan which is streaking and smudging proof and not giving off a tattletale carroty blush is one issue perplexing several women.
Physicians may possibly have the resolution to it with a cream capable of triggering the innate tanning system of the skin sans the requirement of exposure to the sun’s harmful ultraviolet rays.
On rubbing over the skin, the cream stimulates the manufacture of melanin which is the darkish pigment requisite for tanning. And triggering the innate mechanism would translate to the bronzed outcome looking as true as the actual thing. What is even better is that the fake tanning shields the skin from the ravages of the sun, curbing the chances of cancers developing.
One of the study scientists David Fisher stated that their prime objective was to [...]
PLX4032 Drug Treatment – Drastic Shrinkage of Lethal Advanced Melanoma Tumors
An investigative targeted cancer medicine shrivelled advanced staging melanoma tumors among eighty-one percent of the cases. These patients had a lethal and difficult-in-treating type of cancer, according to physicians.
The study results were part of a preliminary stage trial employed for determining the ideal dosage of the investigational PLX4032 medicine currently in the later phase of scientific studies. It has been created for targeting tumor cells carrying a BRAF mutation in a gene. Roche is the maker of this innovatory medicine that was part of a study which appeared in the ‘New England Journal of Medicine’.
During the trial, the drug use translated to total reduction of the tumors in duo patients whereas in twenty-four other patients, there was over thirty percent tumor shrinkage.
Sunbed Use among Teens Doubles Skin Cancer Risk
Teens who opt for sunbeds are almost twofold as likely to be identified with a highly lethal type of skin cancer as compared to the ones who kept away from tanning salons altogether, a research has uncovered.
The study shows that the sooner sunbed usage is started, higher is the risk of getting a fatal melanoma prior to the age of forty.
This has shown that those people who commenced prior to turning twenty have an eighty-eight percent greater likelihood of being detected with a mortal melanoma as compared to individuals never having opted for sunbeds.
The study – foremost of its type for looking into sunbed use and skin cancer diagnosis at younger age is bound to adjoin additional bearing to the mounting campaigns for a complete prohibition on sunbed use.
The research indicates [...]
Why Sun Protection Creams often fail to Curb Skin Cancer Cases?
The tendency to slather on sun protection creams over our bodies the moment a glint of sun shine appears has become customary. Sun safety consciousness has risen in the past ten years and millions are shelled out on brands for warding off the sun’s damaging rays.
In spite of this, skin cancer cases continue to augment unabated and the key reason is being overly exposed to the sun’s rays. Can this surge in skin cancer cases be due to using or misusing sun protection products which could be causing as many issues as they endeavour to resolve?
Majority of the sunscreen products are broad-spectrum, offering defence from the ageing ultra-violet A (UVA) rays that are causal to skin harm and untimely skin wrinkling and the greater strength ultraviolet B (UVB) rays causing sunburns.
Swift Tumor-Blasting ‘Holy Grail’ Cancer Jab – A Notable Advancement in Combating Malignant Melanoma
Researchers have come up with a new-fangled vaccine which they are anticipating to be a ‘holy grail’ treatment for cancer. Testing of this therapy would be carried out on patients from Britain over the time span of the subsequent couple of months and is hoped to have a reversing and also curative effect on a highly grave type of skin cancer, malignant melanoma. In case the treatment manages to garner success in the larger trials, it is hoped that novel types could be created for combating other types of cancers inclusive of prostate, breast. Specialists state that this novel treatment could also halt cancer from occurring in the foremost instant among people.
Drug manufacturers behind the development of the new cancer jab have made claims about the vaccine being capable of treating as [...]
Gaining an Insight into Skin Cancer Types
The prevalent types of skin cancer are malignant melanoma and non-melanoma skin cancers both of which have high cure rates when spotted and treated in their preliminary stages. Those with a past of skin cancer are more likely to develop it yet again and hence must ideally get checked up on a yearly basis.
Malignant melanoma, particularly in the advanced staging is grave and treating it is tricky.
Melanoma though not as prevalent as the other skin cancer kinds, however is quite grave and lethal. The probable symptoms of melanoma comprise of a variation in the way the mole appears or in the pigmented spot. One must seek medical consultation in case a mole has altered its extent, outline or hue, crooked edging, having multiple hues or tones, irregular or is causing scratching, oozing [...]
A Primer on Melanomas
Melanoma is a form of skin cancer though less prevalent than the other skin cancer types, however is more grave as it could not just inflict the exterior skin surface but could even reach the internal structures like organ or bone. Providentially, there is treatment for melanoma in case it has been diagnosed and treated early on.
Causes of Melanoma
Melanoma could develop due to excessive exposure to the sun that leads to healthy skin tissue turning anomalous. Such irregular cells then have uninhibited growth, assaulting the adjoining normal tissues.
Melanoma has a tendency of running in kin lines and there are several aspects of one’s kin settings that could raise likelihood of developing the condition. For instance, one could have moles that are unusual or uncharacteristic (atypical) [...]
It Pays Knowing Your ABCDEs of Skin Cancer
Majority of the moles present on an individual’s body appear alike each other. Moles or freckles that appear dissimilar to the others present on the body or which have a diameter more than six mms or any features of the ABCDE’s of melanoma skin cancer must be evaluated by a skin specialist as it might be malignant. The ABCDE’s are crucial traits to be taken into consideration while evaluating moles or other forms of growths present on the skin’s surface.
A – Asymmetry
Asymmetry is an indicator of two halves not bearing any evenness. Normal moles exhibit symmetry. While self-examining the mole or freckle a made-up line could be drawn in its centre and comparing the left and right half or getting it evaluated by a skin specialist.
In case the bordering or rims of the [...]
Gaining an Insight into Pre-malignant Skin Lesions and Skin Cancer
Similar to several forms of cancers, skin cancers inclusive of squamous and basal cell cancer, melanomas, begin as pre-malignant lesions - variations in the skin that are non-cancerous, however could eventually turn malignant over spans of time. An approximate forty to fifty percent of individuals having fair-skin that manage to survive to the ripe age of sixty-five would get one form of skin cancer in the least case scenario. Hence it is crucial to spot the caveat signs of skin cancer as it is treatable when detected early on.
Solar or Actinic Keratosis
The small-sized, flake-like patchy appearances on the skin that arise due to excessively being exposed to the sun, prevalently noticed in the head, neck or the upper extremity, however could develop in any other area of the body. These are [...]
Pioneering Feat Of Genetic Mapping Of Lung Cancer And Melanoma
Researchers from Britain have made a landmark discovery wherein they were able to do the genetic mapping of two widespread cancer forms.
The mapping has unravelled the DNA mutations that cause cancers inflicting the skin and the lung, the finding of which could alter the manner of diagnosis and treatment of these ailments in the imminent future.
Cancers are the consequence of the harm done to the genes i.e., mutations in DNA which are elicited by factors that are environment-related like tobacco, exposure to detrimental chemicals or ultraviolet radiations that leads to the cells growing uncontrollably.
Researchers at the Wellcome Trust Sanger Institute, Britain along with their associates have be able to map this genetic harm from the tumours of 2 patients ailing from lung cancer and [...]
Mohs Micrographic Surgery – Superlative Treatment Procedure For Non-Melanoma Skin Cancer
Skin cancer is the widespread form of cancer wherein there in an anomalous increase of the cells present in the skin. Early diagnosis and treatment would always cure skin cancer. Majority of the skin cancers are of the nonmelanoma kind. Skin cancer types comprise of two key forms, namely:
Basal cell skin cancer
Majority of the nonmelanoma cancers belong to this form. It could mar deeply located tissues like muscles and bones. It rarely ever metastasizes to other areas of the body.
Squamous cell skin cancer
This form is less prevalent and mostly begins in the skin which has faced injury or infection. It at times metastasizes to other areas of the body.
Mohs micrographic surgery
This form of surgery comprises the removal of skin cancer a single layer in an instant and microscopically [...]
Radiation Lowers Chances Of Malignant Melanoma Relapsing
Scientists have pegged their novel discovery as ‘The Foremost Real Advancement in Malignant Melanoma in fifteen years’.
The newest study indicates that employing Radiation as Malignant Melanoma treatment reduces the likelihood of Melanoma coming back among those individuals having high risk of relapse.
Scientists conducted the study on more than two hundred persons having melanoma at elevated risk of having their cancer relapsing subsequent to surgery as the disease had metastasized to the lymph nodes.
Merely nineteen percent of those who had their lymph nodes treated by undergoing radiation following surgery experienced a relapse of the melanoma in their lymph nodes in the span of the subsequent 2 years.
On the other hand, the cancer relapsed in thirty-one percent of individuals [...]
