About Skin Cancer
What is Skin Cancer?
Skin cancer is the uncontrolled growth of abnormal skin cells. It occurs when damaged skin cells do not replicate correctly during the normal course of repair. These new irregular cells can trigger DNA mutations or genetic defects that multiply rapidly and form malignant tumours.
Who can Skin Cancer Affect?
Skin cancers account for around 80% of all newly diagnosed cancers. Approximately, 66% of Australians will be diagnosed with skin cancer, this almost three times the rate seen in the US or the UK. Annually, over 750,000 people are treated for non-melanoma skin cancers in Australia. These non-melanoma skin cancers are twice as common in men. Melanoma skin cancer affects over 12,000 Australians annually, it is the most common cancer among Australian between 15-44 years.
Risk Factors for Skin Cancer
Every Australian is at risk of skin cancer, though the risk increases as you get older.
- Prior Diagnosis: People who have had a skin cancer previously are at risk for developing others over the years, either in the same area or elsewhere on the body.
- Exposure to Sunshine: Both long-term sun exposure over your lifetime and occasional extended, intense exposure (typically leading to sunburn) combine to cause damage that can lead to skin cancer
- Age: The incidence increases for both males and females over 50 years old, but as the number of new cases has increased sharply each year in the last few decades, the average age of patients at onset has steadily decreased.
- Genetic Factors;
- Fair skin
- Blond or Red hair
- Blue, Green, or Grey eyes
- Family history of skin cancer
Skin Cancer Checks
Skin Cancer Facts
Skin Cancer or Skin Carcinomas are malignant, abnormal, uncontrolled growths or lesions that arise in the skin.
90% of skin cancers are due to overexposure to UV light, either from the sunlight or solariums. The best way to survive skin cancer Is early diagnosis and treatment.
Unfortunately they are very common and 66% Australians will be diagnosed with skin cancer before they turn 70. This is almost three times the rate seen in the US or the UK.
What is a Skin Cancer Check?
There is currently no formal screening program for skin cancers in Australia. It is recommended that people become familiar with their skin. If you notice any changes consult your doctor.
It is generally recommended that you have a skin cancer screening test once every two years. This should be performed more regularly if you are at higher risk of developing skin cancers. Higher risk patients are those mentioned below.
If you notice any of these changes, arrange an appointment with our Doctors for a skin check immediately.
During a skin check our doctor will closely examine your moles and other skin lesions with a specialised instrument known as a dermatoscope to aid early detection of changes of skin cancers, and advise on possible treatment options.
Skin Cancer Education:
Knowledge is power, which is why we want you to know what lesions to look out for and how to protect yourself and your family. Many patients have identified skin cancer on their friends and family members after their skin check appointment with us.
Full Skin Cancer Checking Service;
As part of this service, one of our trained staff perform a systematic total body check and generates digital dermoscopic and total body images:
- A doctor will then examine each patient to check each mole and lesion on their skin. They will discuss a treatment program if required, and advise on the best long term management and prevention.
- Some treatment may be performed during this skin check appointment if necessary and the patient requests it.
Each total body skin check takes up to half an hour and is advised for everyone over the age of 18 on an annual basis.
Surgical Excision
Surgical removal or excision of skin cancers is the most common treatment.
Non-melanoma skin cancers are almost always surgically removed under local anaesthetic and this is the safest form of treatment due to the potential of Basal or Squamous Cell Carcinomas to spread.
This approach offers:
- high cure rates
- Is immediate,
- Lesions are sent off for histology and margins are checked to ensure complete clearance
In more advanced skin cancers, some of the surrounding tissue may also be removed to make sure that all of the cancerous cells are cleared.
Excision Treatment Process:
After careful administration of local anaesthetic, the Doctor uses a scalpel to remove the entire growth, along with surrounding apparently normal skin as a safety margin. The wound around the surgical site is then closed with sutures (stitches).
Excision Treatment Recovery
For a few days post excision there may be minor bruising and swelling. Scarring is usually minimal. Pain or discomfort is minor. Typically, where sutures are used, they are removed soon afterwards.
Surgical Excision Prognosis
Studies indicate the cure rate for primary tumours with this technique is around 92 percent. Clearance rates for recurrent Basal or Squamous Cell Carcinomas are lower around 77 percent
