The actual number of moles increases risk, but the size of the moles needs be considered. Those with 10 larger moles of over 1 cm (0.4 in.) are at more risk than those with a higher number (50-99) of smaller moles.

What would cause the pressure of the gas to increase?
The answer to this question lies in the ideal gas law: PV=nrT in which: P = presssure V = Volume n = number of moles r = ideal gas constant T = temperature because we want P to increase, we can achieve that in a couple of ways: 1. decrease the volume 2. increase the number of moles 3. increase the temperature. Value of r cannot change; it is a constant.
What would the effect on temperature and volume be if you changed the number of moles of gas in a container?
In a container the volume remain constant but the pressure increase.
Is number of moles vector or scalar?
There is no direction in number of moles, so it is scalar.
What is the number of moles in 0.025 g NH42Cr2O7?
The number of moles 9,92.10e-5.
What happens to the volume of a gas when the number of moles is doubled (all else held constant)?
At a constant volume the pressure increase.
Are moles benign?
Most moles are benign, but atypical moles (dysplastic nevi) may develop into malignant melanoma, a potentially fatal form of skin cancer. Atypical moles are usually hereditary.
How is the device known as a dermatoscope used in diagnosing malignant melanoma?
The doctor may also use a dermatoscope to examine the mole prior to removal. The dermatoscope, which can be used to distinguish between benign moles and melanomas, is an instrument that resembles an ophthalmoscope.
Colored pigmented lesion of the skin a mole?
Most of the pigmented lesions are moles. Other benign pigmented lesions are haemangioma, dermatofibroma, solar keratoses. Malignant pigmented lesions are malignant melanoma, Bowen's disease, and basal cell carcinoma. Moles should be carefully watched for change in size, colour, ulceration, bleeding and crusting and avoid exposure to too much Sunlight and the use of sun lotion with UVA / UVB protection.
I noticed just recently that a mole I have has changed colour. It used to be a solid orange-y colour but has adopted a darker ring around the outside. Why is this?
Please, show it to a dermatologist as soon as possible! Malignant Melanoma could arise from moles. Malignant Melanoma is a type of skin cancer, which does not stay just in the skin, but could spread to other parts/organs of the body. When a mole changes in size, colour, surface, ulcerate, or bleed, it is a wise move to show it to a doctor (preferable a dermatologist), just to be sure.
Can dogs form moles?
Yes, dogs can have moles, as can other animals. A mole can be melanoma cancer in dogs, but don't be alarmed because that is rare. Moles are very common.
Can moles cause cancer?
Moles do not cause cancer, however, certain cancers, such as melanoma, can present with moles. Most moles aren't cancerous, but if you feel concerned, you should see a doctor, as the cancerous moles are very distinguishable from the regular moles.
If the volume and number of moles of gas are held constant as the temperature increase what will the pressure do?
The volume decrease.
What gives you melonoma?
Melanoma is a type of skin cancer that develops in the melanocytes, which are the pigment-producing cells in the skin. The exact cause of melanoma is not fully understood, but it is believed to be a combination of genetic predisposition and exposure to ultraviolet (UV) radiation from the sun or artificial sources such as tanning beds. Here are some factors that may increase the risk of developing melanoma: UV Radiation Exposure: Exposure to UV radiation from the sun or indoor tanning devices is a major risk factor for melanoma. UV radiation damages the DNA in skin cells, increasing the likelihood of mutations that can lead to the development of cancerous growths. Fair Skin: People with fair skin, light hair, and light eyes are at higher risk of developing melanoma because they have less melanin, which provides natural protection against UV radiation. History of Sunburns: A history of severe sunburns, especially during childhood or adolescence, can increase the risk of melanoma later in life. Sunburns indicate overexposure to UV radiation, which can damage the DNA in skin cells and increase the risk of cancer. Family History: Individuals with a family history of melanoma or other types of skin cancer have an increased risk of developing melanoma themselves. Certain genetic mutations may predispose individuals to melanoma, although most cases of melanoma occur in people without a family history of the disease. Moles: Having numerous moles (nevi) or atypical moles (dysplastic nevi) may increase the risk of melanoma. Changes in the size, shape, color, or texture of moles may indicate the development of melanoma or other skin cancers. Weakened Immune System: People with weakened immune systems, such as those with HIV/AIDS or who are undergoing immunosuppressive therapy, may have an increased risk of developing melanoma. Age: While melanoma can occur at any age, the risk increases with age, with most cases diagnosed in adults over the age of 50. It's important to note that while these factors may increase the risk of developing melanoma, not everyone with these risk factors will develop the disease. Additionally, melanoma can occur in individuals without any known risk factors. Practicing sun safety, including wearing sunscreen, protective clothing, and seeking shade, is essential for reducing the risk of melanoma and other types of skin cancer. Regular skin self-examinations and annual skin checks by a healthcare provider can help detect melanoma early when it is most treatable. If you notice any changes in your skin, such as new moles, changes in existing moles, or other suspicious growths, it's important to seek prompt medical attention.
Why does an increase in the number of molecules increase the pressure?
The great the density the higher the air pessure.
What are some of the symptoms of melanoma?
Some of the melanoma symptoms that your doctor would be looking for is the change in any mole. If it has grown quickly and has an irregular shape, if the colour is not constant throughout the mole and it is different to other moles you might have, he will be inclined to think that you have melanoma.
Is it common to have two separate malignant melanoma skin sites and not feel or show any symptoms of the disease?
About 10 % of people who have had a primary melanoma will end up developing a second primary melanoma at some point in their life. Melanoma does not usually show symptoms but itching of a mole or lesion is reported by some patients. The signs of a melanoma are a mole that has changed. Change can be asymmetry of the lesion (one side does not match the other), Borders change (the edges look fuzzy or scalloped), Color change (mole has turned dark black, red, purple), and Difference (any mole that changes and looks different than before or different than your other moles). This is know as the A B C D 's of melanoma. Also melanoma can form on skin that has not previously had a mole associated with it.
Take Potential Melanoma Symptoms Seriously?
Melanoma is a serious skin cancer with a high mortality rate if left untreated. If caught early, however, the prognosis is extremely good. Melanomas in the early stages can usually be completely removed with a simple visit to a dermatologist's office. It is very important for everyone to be on the lookout for early melanoma symptoms. It is better to be safe than sorry, and people who think they may have early melanoma symptoms should immediately schedule an appointment with a dermatologist. The symptoms of melanoma are not difficult to spot with the proper attention. To spot melanoma signs early, people should regularly examine their moles. A healthy mole tends to be smaller than an eraser tip, even in color, even in border, symmetrical, and stable. Moles that do not display these characteristics may be potential melanoma sites. Melanoma symptoms often first appear as changes to a current mole. It may be a potential sign of cancer if a mole suddenly starts growing rapidly. If a mole changes color or shape, it could also be a sign of melanoma. If new moles start popping up around a strange-looking mole, these moles could be dangerous satellite moles. Such moles signify that a melanoma may be spreading. Melanoma symptoms also often appear as brand new moles. A melanoma will almost always have an atypical appearance. It will likely be highly asymmetrical. It may have an irregular border. It may have many colors instead of just one color. It may be very large. If a mole is larger than six millimeters in diameter, it should be examined by a dermatologist. Melanoma does not just occur on skin areas that are exposed to sunlight. People should also check for atypical moles on the soles of their feet, the palms of their hands, and on other areas that are not commonly exposed to the sun. While melanoma symptoms are often painless, some melanomas might ooze or itch. Although people with pale skin and an abundance of moles are at high risk for melanoma, the cancer can strike people of all ethnic groups. For this reason, everyone should visit a dermatologist regularly for a mole check.
