Lung cancer is the uncontrolled growth of abnormal cells in one or both lungs. These abnormal cells do not carry out the functions of normal lung cells and do not develop into healthy lung tissue. As they grow, the abnormal cells can form tumors and interfere with the functioning of the lung, which provides oxygen to the body via the blood.

Lung cancer is the most common cause of death due to cancer in both men and women throughout the world. According to the U.S. National Cancer Institute, approximately one out of every 14 men and women in the U.S. is diagnosed with cancer of the lung at some point in their lifetime. Lung cancer is predominantly a disease of the elderly; almost 70% of people diagnosed with lung cancer are over 65 years of age, while less than 3% of lung cancers occur in people under 45 years of age.

What Causes Lung Cancer?

The development of lung cancer is strongly associated with cigarette smoking, approximately 90% of lung cancers are attributable to use of tobacco. Pipe and cigar smoking can also cause lung cancer, but the risk is not as high as with cigarette smoking. Tobacco smoke contains more than 4,000 chemical compounds, many of which are cancer causing (carcinogens). Passive smoking, i.e. the inhalation of tobacco smoke by non-smokers who live or work with smokers, is also an established risk factor for the development of lung cancer.

Genetic susceptibility (i.e. family history) may play a role in the development of lung cancer. Other causes of lung cancer include air pollution (from vehicles, industry, and power generation) and inhalation of asbestos fibres (usually in the workplace).

Lung Cancer Symptoms

Early symptoms and signs of lung cancer

There may be no symptoms at the onset of the disease. When present, common symptoms of lung cancer may include:

Coughing: This includes a persistent cough that doesn't go away or changes to a chronic smoker's cough, such as more coughing or pain.
Coughing up blood: Coughing up blood or rust-colored sputum (spit or phlegm) should always be discussed with your doctor.
Breathing Difficulties: Shortness of breath, wheezing or noisy breathing (called stridor) may all be signs of lung cancer.
Loss of Appetite: Many cancers cause changes in appetite, which may lead to unintended weight loss.
Fatigue: It is common to feel weak or excessively tired.
Recurring infections: Recurring infections, like bronchitis or pneumonia, may be one of the signs of lung cancer.
Signs of advanced stages of lung cancer

Advanced stages of lung cancer are often characterized by the spread of cancer to distant sites in the body. This may affect the bones, liver or brain. As other parts of the body are affected, new lung cancer symptoms may develop, including:

Bone pain
Swelling of the face, arms or neck
Headaches, dizziness or limbs that become weak or numb
Jaundice
Lumps in the neck or collar-bone region
Treatment

Treatment for cancer involves a combination of surgery to remove cancer cells, chemotherapy and radiation therapy to kill cancer cells. Lung cancer is incurable unless complete surgical removal of the tumour cells can be achieved. Surgery is the most effective treatment for lung cancer, but only a few percentage of lung cancers are suitable for surgery i.e. Stage I and II NSCLC and cancer that has not spread beyond the lung.

Radiation therapy may be used for both NSCLC and SCLC and is a good option for people who are not suitable for surgery or who refuse surgery. Chemotherapy is used for both NSCLC and SCLC. Chemotherapy drugs may be given alone or in combination with surgery or radiation therapy. Chemotherapy is the treatment of first choice for SCLC since it has usually spread extensively in the body by the time it has been diagnosed.

Also used in the treatment of lung cancer are targeted therapies. These are drugs (gefitinib and erlotinib) or antibodies (cetuximab, bevacizumab) that block the growth and spread of cancer by interfering with specific molecules involved in tumor growth and progression. They are used in some patients with NSCLC that does not respond to standard chemotherapy.

Lung Cancer: Causes, Symptoms and Treatments

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!

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.

4. Room fresheners - air-fresheners, like deodorants have vcos which are toxic and extremely harmful for us. They aggravate asthma and even affect reproductive development. They have hazardous components which can be cancerous. It is advisable to use essential oils.

5. Scented candles - scented candles mostly have wicks made of lead. While they serve a good purpose, there is no point in using something which gives momentary relief but can prove hazardous in the long run.

6. Certain paints - permanent markers, acrylic paints, solvents, etc contain hazardous chemicals which have been associated with occurrences of cancer, allergies and oral damages.

7. Gardening chemicals - household pesticides, herbicides or fungicides that we often use in gardens can contain carcinogenic materials which are believed to cause lymphomas and breast cancer (in animal models).

8. Plastic food/beverage containers - plastic materials containing bpa, or bisphenol a are believed to dangerous for health. So when one is using plastic bottle or food container make sure it is bpa free.

9. Nonstick cookware - cooking utensils which are made with a nonstick coating (teflon) is suspected to be a carcinogen. The main chemical in nonstick coatings is perfluorooctanoic acid (pfoa) is known to cause cancer. Glass, cast iron, copper, and ceramic or pfoa free nonstick cookwares are safe.

9 Things You Must Watch To Make Your Home Cancer Free

With the recent number of breast cancer cases on the rise, it is important that we should get the examination done on a regular basis as a preventive measure. Even if someone is suffering from it, it is important that we should make an effort and learn about.

If you have breast cancer then a surgery will be part of your treatment. Based on the condition, surgery will be carried out due to any of the following reasons:
1. To remove the cancerous tissues from the breast
2. To reconstruct the breast once the cancer is removed
3. To check whether the cancer has spread to the lymph nodes below the arm
4. To treat symptoms of cancer that has progressed to an advanced stage

Breast cancer surgery may be classified into two types
1. Mastectomy: Mastectomy involves removing the entire breast; tissues in the adjoining region may also be removed. A double mastectomy is a procedure where both the breasts are removed.
2. Breast-conserving surgery: In this surgery, only parts of the breast affected by cancer are removed. The area of the breast that is to be removed will depend on the severity of the cancer. Some healthy tissues may also be removed in this surgery.

Usually, if a woman is in the initial stages of cancer then she may opt for the latter as it entails removing parts of the breast. They may also undergo radiation therapy along with these surgeries.
For checking if the cancer has spread to the lymph nodes below the arm, the lymph nodes are removed from the body. Once they are removed, they are studied under a microscope to check if it has spread, if yes then the extent of their damage. This procedure is carried out along with the surgery to remove the cancer.

Once the mastectomy procedure is completed, you can opt for a breast reconstruction surgery to rebuild the area. You may opt for this procedure at the time of breast cancer removal or at a later stage. If you are considering breast reconstruction surgery then you should discuss it with your surgeon.

Surgery is sometimes not used to treat cancer, but in slowing the progression of cancer or even reducing its symptoms.It is important you talk to your surgeon before the procedure to understand the goal of the surgery.

Surgical Procedure for Treating Breast Cancer

A prostate operation involves the removal of a part of the prostate gland or sometimes the removal of the entire prostate gland. Such a surgery is a serious one and several recovery tips must be followed by a patient to ensure quick and successful healing. 

Here are some important tips for recuperating from a prostate operation:

After the surgery, you need to spend up to three days in the hospital for initial recovery. You might be given fluids, which go directly into your veins until you fully recover from anesthesia.
After the operation, normal urination will be disrupted in the beginning, as the urethra stays swollen. Urinating gets a little difficult and uncomfortable for a few days after the removal of the catheter.
You may feel fatigued and may feel under the weather for some weeks after a prostate operation. So you must take things easy for at least two months.
Avoid lifting or moving heavy objects for some weeks following the surgery. Do not perform any exercise, which causes strain. You should ask your friends and family members to carry out chores for you.
After becoming slightly stable you should start gentle exercises. Walking is an effective remedy, which helps in blood circulation and lowers the risk of getting blood clots in the legs.
You should drink lots of water during the recovery stage. This will reduce the risk of getting a urinary tract infection and also help in clearing any trace of blood from your urine.
For improving bladder control, you should perform several pelvic floor exercises.
In case of any kind of pain, you can take over the counter painkillers to ease the pain.
It will take you a time span of three to six weeks for total recovery after a prostate operation. You should consult your surgeon about the best time to return to normal daily activities.
You can get back to work soon, but it depends on your nature of work. Office jobs are not much of a problem, but in case of physical labour, more time is needed before you can resume your duties.
Activities such as driving can be started quite soon after initial recovery. However, it varies from person to person. Some people may get back to driving within two weeks while some may need a month.
You have to wait for 6 to 8 weeks after a prostate operation before getting back to sexual activities.
In case you experience high fever, pain during urination or the inability to urinate, you must consult your doctor immediately.
It takes a person several weeks to recover from a prostate operation completely. Initially, total rest is required. But eventually, he can return to normal activities and lead a healthy life.
