Lung cancer is the cancer killer of both men and women in the world. When you think of risk factors for lung cancer, what comes to mind? Most of us think about the risk associated with smoking cigarettes, but did you know that air pollution can also cause lung cancer? Overwhelming evidence shows that particle pollution in the outdoor air we breathe like that coming from vehicle exhaust, coal-fired power plants and other industrial sources - can cause lung cancer. Particle pollution increases the risk of dying early, heart disease and asthma attacks, and it can also interfere with the growth and function of the lungs. 

What is Particle Pollution?

Particle pollution is a mix of tiny solid and liquid particles in the air and can be made up of a number of components, such as acids, organic chemicals, metals, soil and dust particles. It can be emitted directly from wood stoves, forest fires, vehicles and other sources, and it can also form from other types of pollution that come from sources like power plants. 

Why does particle pollution harm our bodies?

While breathing in larger sizes of particle pollution can be harmful to our health, smaller particles are more dangerous. Bigger particles can irritate your eyes, nose and throat, but our natural defenses help us to cough or sneeze them out of our bodies. Unfortunately, those defenses don't keep out smaller particles, which get trapped deep in the lungs and can even get into the bloodstream, causing damage to our health.



Who is most at risk?

As for who is at risk for health problems from breathing in particle pollution. Those who live where particle pollution levels are high is at risk. Some people face higher risk, including children, the elderly, people with lung and heart disease and diabetes, people with low incomes, and people who work or exercise outdoors.

How do we protect ourselves from particle pollution?

Check the air quality index forecast for the day and limit your activity if pollution levels are high. Avoid exercising along heavily traveled highways regardless of the overall forecast.

As individuals, we can play our part in reducing air pollution levels by trying to avoid creating more of it. Choosing  active travel  options where possible, like walking and cycling, can help reduce pollution levels from transport and is also a great way to be more active, which is linked to a reduced risk of cancer and other diseases.

The Connection Between Lung Cancer & Outdoor Air Pollution!

Breast examination is a way of detecting early changes that help in detecting lumps or other growth in the breast. This is a manual form of examination that may be carried out by the doctor or even by the patient. This kind of examination helps in detecting the onset of breast cancer and helps in successful treatment of the same. It is an essential screening strategy that all women must go through. Let us cast a glance on the various details regarding this examination, and also how frequently it must be conducted.

Age: Women who have reached the age of 18 are said to have matured physically and sexually. They should perform this examination once they have reached the said age in order to detect any anomalies in the way the physical changes occur in the breast tissue.
Procedure: One should begin by looking at one's reflection in the mirror to find any rashes or dimpling in the breasts. The shape, size and colour of the breasts and nipples must also be studied so as to check for any anomalies. Inverted nipples, redness and soreness must also be reported to the doctor. Once you are done checking the visuals, you can raise your arms and look for any changes. Then, you will need to lie down and feel your breasts by using a circular motion. The finger pads must be used in order to check for any lumps. One must start from the centre and move the breasts sideways. Any wet and slippery feeling must be reported to the doctor immediately.
Pressure: During the breast examination, you must use light pressure for the skin and tissue that lie beneath the breasts, while medium to moderate pressure should be used for the middle portion of the breasts. One must use a firm hand to check the tissue that lies at the back of the breasts, near the rib cage.
Frequency: One must get into the habit of conducting a breast examination at least once a fortnight or once a month, without fail. You can also go to the gynaecologist for an examination in case you are not confident of conducting it on your own with proper movements and accuracy. You may also journalise your breast examination findings.
Menstrual Cycles: When you are going through your menstrual cycle or period, it is important to remember that your breasts can become tender just before or after the start of the cycle. So, do not panic if you think you have found a lump or any other growth at this time. It is best to check again after a week and then visit the doctor about checking the same.

How Frequently Should a Breast Examination Be Done?

Photodynamic therapy or PDT is a relatively new and non-invasive treatment for non melanomaskin cancer. It is mostly used in cases where the cancer is superficial and has not spread too deep. PDT is used mostly to treat Actinic Keratoses on the face and scalp, Basal cell carcinomas, Bowen s disease, as well as other conditions such as head and neck, mouth, lung and gullet cancer.

How does it work?
This treatment involves the use of a drug known as photosensitize or a photosensitizing agent with a specific type of light. When the photosensitizing agents get exposed to a light of a specific wavelength, a form of oxygen is produced, which eliminates nearby cancer cells. Every photosensitizer gets activated by the special light. The wavelength of the light determines how much it can penetrate into the body.

Process of Photodynamic therapy
Skin cancer is cured by PDT in several steps. The first step involves the injection of a photosensitizer into the patient s bloodstream. The blood cells absorb the agent all over the body, but in the cancer cells, it stays for a longer duration. Within 72 hours after the injection is given, the skin is exposed to light. The photosensitizer agent present in the cancer affected cells absorbs the light. An active oxygen form gets produced, which kills the cancer cells.

Other than killing the cancer cells directly, PDT uses two other ways to destroy cancerous tumors. The blood vessels in the tumor are affected, which leads to its death. The immune system also gets charged up and activated for fighting the cancer cells.

The light used for PDT is usually in the form of a laser. LEDs are also used to treat tumors present on the surface of the skin. The primary photosensitizing agent used in PDT is called porfimer sodium or Photofrin.

PDT can be undertaken in the outpatient department in a hospital. After taking the treatment, you have to keep the cancer affected area of the skin dry and covered for 36 hours. The area should be treated with care while showering. In case of thick skin lesions, repeat treatments are required within 4 weeks.

When is PDT used for skin cancer
PDT can be undertaken instead of surgery for treating basal cell cancer, Bowen s disease and actinic keratosis. PDT is used in cases where surgeries are required. It is used to treat large skin cancers, which are not very deep and in the case when several cancers develop in an area. For many skin conditions, PDT is a better remedy than undergoing a surgery.

Advantages of PDT

    There are no long term side effects.
    The process is less invasive compared to surgery.
    A very short time is taken for this therapy to be undertaken.
    The process can be repeated several times in the same area.
    Very less scarring takes place in the affected area.
    The cost of this procedure is lesser than surgery.

Treating Skin Cancer with Photodynamic Therapy

Skin cancer occurs when the DNA of the cells undergo mutations, thus causing unsystematic cell growth which evolve into a cancerous mass. This abnormality stems from the over-exposure of your skin to the Ultraviolet Radiations of the sun. 

However, there are other factors too that escalate the risks of skin cancer.

Fairer skin tone: Inadequate pigmentation or melanin content in the skin offers less protection against the harmful UV radiations. Having red or blond hair or light-colored eyes makes you more vulnerable to this condition.
Sunburns: A history of sunburns can often be the root cause behind skin cancer.
Excessive exposure to the sun: If you spend a considerable amount of time under the sun and especially if your skin is not protected by clothing or sunscreen, you tend to get a tan. A tan is the skin s response to extreme UV radiations.
Moles: Abnormally large moles, known as dysplastic nevi, are more likely to turn malignant. Watch out for any change in the texture of the moles, which is one of the most important symptoms of skin cancer.
Family history: According to studies, genes are considered to be one of the causes behind skin cancer. Hence, a family history of this condition could spell trouble for one.
Personal history: Having suffered from skin cancer previously in life could endanger one even more.
Pre-cancerous skin injury: Skin lesions, also known as actinic keratosis, make you prone to developing pre-cancerous growths on the skin. These could appear as scaly rough patches, ranging from brown to pink in color. They usually crop up on the hands, head and faces of people who are comparatively of a fairer skin tone.
A weak immune system: People having a poor immunity system, including the ones affected by HIV/AIDS or are on immunosuppressant drugs which follow any organ transplantation have greater risks of developing cancer.
Exposure to radiation: Radiation therapy is an often used treatment method for treating various skin conditions such as acne and eczema. Having been exposed to radiations, one could be indisposed to this condition even more.
Exposure to certain chemicals: Exposure to certain substances such as arsenic might increase your vulnerability manifold.

Skin Cancer - 10 Things That Can Increase Your Risk!

According to a major study that provides a connection between height and cancer, it is stated that taller people are more prone to developing cancer. Research has found that the risk of developing any kind of cancer in women rises by 18% for an increase of every 10 cm in height. In men, the risk rises by 11%, even though height is not as major a factor as are obesity, smoking and a bad, unhealthy diet.

Several reasons have been put forward for the above statement. One of the reasons is that the number of body cells in taller people is more than people with average height. This leads to an increase in the number of cells which could potentially turn malignant.

While individually analysing the impact of height on different cancer forms, it was found that the highest increase in risk was in skin cancer (30% for every 10 cm increase in height), while a 20% increase was noted in taller women developing breast cancer.

Development of cancer in regions including the colon and rectum is known as colorectal cancer. Long legs have been surprisingly associated with this form of cancer. In comparison with shorter people, it was reported that taller people had a higher risk percentage of developing colorectal cancer. Two hypotheses regarding the formation of colorectal cancer have been developed. One hypothesis is that taller people have longer colons, which in turn result in more surface area where colon cancer can develop. The other hypothesis is that taller people experience increased levels of growth hormones. These particularly affect the length of their legs. The growth hormone called 'insulin-like growth factor 1' is increased during puberty and is considered to be a risk factor for colorectal cancers occurring at later stages.

Being Taller Increases Your Risk of Cancer!

One of the things that Shannen Doherty and Rita Wilson, the wife of Tom Hanks, have in common, apart from their fame is that both were affected by breast cancer. No matter how normal a person may seem, breast cancer can strike anyone. In fact, it usually strikes one in eight women. So, it makes good sense to know what it can appear as!
Breast cancer makes up a rather big amount of the general cancer cases as 15% of the cancer cases which are reported on a yearly basis are usually breast cancer cases. That being said, there are quite a few things which can be done in order to reduce a person s risk to breast cancer.
Prevention is Prudent-
Get Fit: The first thing which should be done is that a reasonable level of fitness should be maintained. Many studies have found that if a person is significantly heavier than her recommended weight, she is at a far great risk to develop all sorts of cancer and breast cancer, in particular, than a person who is able to keep her weight in check. The difference in cancer risk rates is about 40%. This is because a greater amount of fat leads to more estrogen being produced, which increases the risk of breast cancer.
Quit Smoking: While most people associate smoking as something which increases the risk of cancer to the lungs and are not aware that it increases the risk of breast cancer, too. So, the best solution is to kick the habit!
Get Off the Pill: Once a woman crosses past her mid-thirties, she should try to avoid relying on birth control pills to reduce the risk of pregnancy. This is because these pills have an effect which increases the risk of breast cancer, which heightens as a woman gets older. As long as the woman cuts out the use of the pill, the risk quickly gets cut, as well.
Get Regular Check Ups: While screening for breast cancer by making use of mammograms does not cut the risk of it, the screening helps detect breast cancer early if it does exist. As a result, a woman has a much better chance of fighting breast cancer. So, a woman who is past the age of forty should try to have a mammogram on an annual basis with the frequency of the same increasing as she gets older. However, it is to be kept in mind that going for a mammogram too often is also not a good idea as the tests themselves pose risks of DNA changes.
Women all around the world are susceptible to breast cancer. While there isn t a 100% chance of avoiding it, taking care of yourself and leading a fit and active lifestyle can significantly cut down your risk of contracting this condition. Remember, your health is in your hands, so the earlier you start, the better!
