Skin Cancer: Diagnosis and Treatment
We will remove your skin cancer lesions and help you feel more confident in your skin as a result.
We offer diagnosis and treatment for skin cancer…
Comedian Jerry Seinfeld once joked on his television show that skin doctors are glorified pimple poppers and they don’t save people’s lives. That was until someone brought up skin cancer and he had to eat his words. Skin Cancer is the most common cancer human acquire and is usually the result of excessive sun exposure. Thankfully we have a whole variety of treatments to address this very common condition.

Skin Cancer
Skin Cancer is the uncontrolled growth of abnormal skin cells. There are several different types of skin cancer to be aware of:
- Basal Cell Carcinoma – the most common, slowest growth rate
- Squamous Cell Carcinoma – slow/moderate growth rate
- Melanoma – less common, more dangerous, rapid growth rate
What Are the Symptoms of Skin Cancer?
The primary symptom of any skin cancer is usually a mole, sore, lump, or growth on the skin. It is important to watch for any pigment changes in sores or bleeding from skin growths, as these are often associated with the development of skin cancer.
A useful method for remembering common symptoms is the ABCD System:
-
- Asymmetry: One half of the abnormal area is different from the other half.
- Borders: The lesion or growth has irregular edges.
- Color: Color changes from one area to another, with shades of tan, brown, or black (sometimes white, red, or blue). A mixture of colors may appear within one sore.
- Diameter: The trouble spot is usually (but not always) larger than 6 mm in diameter — about the size of a pencil eraser.
Non Melanoma Skin Cancers:
Basal Cell Carcinoma
- Appearance of pearly or waxy textured bumps
- White, light pink, flesh-colored or brown discoloration
- Raised skin
- A skin sore that bleeds easily
- A sore that does not heal
- Oozing or crusting spots in a sore
- Appearance of a scar-like sore without having injured the area
- Irregular blood vessels in or around the spot
- A sore with a depressed or sunken area in the middle
Squamous Cell Carcinoma
- Rough, scaly and flat reddish patches/bumps
- Changes in existing warts, mores or sores
- A sore that does not heal
What Are the Causes of Skin Cancer?
Regular exposure to sunlight or ultraviolet radiation is the most common inducer of cancerous cells, especially among people with fair skin, blue or green eyes, with red or blond hair. Other risks include:
- Age
- Living in sunny climates or at high altitudes
- Long-term exposure to high intensity sunlight
- One or more blistering sunburns during childhood
- Use of tanning services/lotions
- Family history of melanoma
- Exposure to cancer causing chemicals, or
- Weakened immune system
Type specific symptoms:
- Basal Cell Carcinoma – develops from abnormal cell growth in the top layer of the epidermis or skin
- Squamous Cell Carcinoma – involves changes in cells in the middle layer of the skin known as squamous cells
- Melanoma – occurs in cells that produce pigment

How Does Photodynamic Therapy Work?
Photodynamic therapy (PDT) uses a light and a light activated medication (photosensitizing medication) that destroys the problem skin tissues.
When the photosensitizing medication is applied to the problem skin tissue and activated by light, the medication produces a toxic reaction that damages the unwanted skin cells. The body will naturally shed these cells producing newer, healthier skin in their place. Levulan is a type of medication that does just this. Once the medicine has had time to incubate on the surface of the skin this gives enough time for the abnormal skin cancer cells to take up the medication (normal cells will not in such a short period of time ie., 4 hours) and then when Blue Light activates the medication, this in turn destroys the skin cancer cells.
What Conditions Does Photodynamic Therapy Treat?
What is the Procedure?
At DermMedica, the average Photodynamic Therapy appointment is 5-30 minutes. Patients are scheduled for a quick 10-15 minute appointment early in the day to receive the application of the photosensitizing medication. Patients can then leave the office while the medication incubates and then return in 2-3 hours for the blue light activation treatment.
What is the Recovery Time?
7-10 days – Common effects during recovery of a Photodynamic Therapy treatment include redness, flaking of the skin, tenderness and irritability. Patients are advised to avoid excessive sun exposure and maintain healthy skin moisture as an important part of the recovery process.
What Are the Expected Results?
Younger, softer, smoother skin is the expected result of a Photodynamic Therapy treatment. Best results are achieved after 2-3 sessions and may require more treatments depending on the severity and scope of the condition being treated.
Frequently Asked Questions
There are a multitude of treatments for skin cancers because there all sorts of types of skin conditions we treat. These range from medical (topical) treatments, to laser and surgical methods. We will discuss which treatments are available and then which ones are preferable for you.
The only way to tell if you have some skin cancer issues is to have a physician look at your skin to tell you this. Sun damage is common, we all have it to one degree or another. Prolonged sun exposure can lead to skin changes that are cancerous in nature such as a basal cell carcinoma or a squamous cell carcinoma and only a physician qualified to diagnose these should give you the answer.
Skin cancer removal treatments are generally covered by your provincial insurance plan. We do however require a referral from your physician to assess the condition initially so we can formulate a treatment plan.
Basal cell cancers do not spontaneously disappear, they usually need to be surgically excised by a physician.
Yes the can, but normally your family doctor can spot them and diagnose them as well.
The best way to check out a suspicious lesion is to be referred to someone who does this all the time like Dr. Crippen does. On your own, look for any lesions that are not like others you have and are unusual looking.
Your doctor should be able to tell you after receiving back the pathology report if everything was removed. This is the only way to tell.
Yes, basal cell cancers are always a risk and should be excised.
This varies between people but Basal cell cancers normally do not metastasize(spread elsewhere) so a bit of a wait is not unusual nor should it affect the outcome.
Melanoma should never be left to grow on it’s own, death is the most likely outcome with this option.
The best thing you can do is avoid excessive UV exposure, use a good sunscreen when outdoors and get your skin checked regularly if you have any odd or concerning lesions.
