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

What menstrual problems are to women, prostate problems are to men. The prostate is a gland in the lower abdomen that aids in the production of semen. The prostate is walnut sized in a young man, but can get enlarged with age. As it grows bigger, it can cause a number of problems. These are commonly seen after a man celebrates his 50th birthday.

There are three common prostate problems faced by men. Some of the symptoms that can tell if a man has a prostate problem are:

1. Difficulty faced while urinating
2. The urge to urinate frequently at night
3. Constant feeling of a full bladder
4. Pain while urinating
5. Blood in the urine

Prostatitis

This can be defined as inflammation of the prostate gland. In most cases the cause of this inflammation is unknown. However, there are two types of prostatitis; bacterial and nonbacterial. While the former reacts well to antibiotics, the latter is more difficult to control. Symptoms of this disease vary from one person to the next. Some of the factors that could trigger this disease are:

1. Chemical irritants
2. Past bacterial infection
3. Dysfunctional pelvic floor muscles
4. Sexual abuse
5. Chronic anxiety

Enlarged prostate

As mentioned earlier, as men get older, the prostate gland tends to grow in size. This growth is benign, but can block the bladder neck and prostatic urethra. This can cause problems urinating and lead to acute urinary retention. This can be very painful. Inserting a catheter can provide temporary relief and help release stored urine. Chronic retention is much less common and is associated with high bladder pressure and can damage the kidneys.

Prostate cancer

Advancing age and family genetic history are said to be the main triggers of prostate cancer. This type of cancer can remain restricted to the prostate gland in its early stages but may spread to the other glands as the cancer advances. This can also cause the growth of secondary tumors in the bones.

The only way to correctly diagnose a prostate problem is with a thorough physical examination. This includes a digital rectal exam where the doctor will insert a gloved finger into your rectum to check the size of your prostate, a blood test, mid stream urine tests and ultrasounds. In some cases a biopsy of the prostate may also be required. Depending on the diagnosis, your doctor may prescribe antibiotics, surgery, radiotherapy or hormone therapy to manage your prostate.

Are You at Risk of a Prostate Disease?

Lumpectomy is a surgery where a cancerous or benign tumour is removed from a breast along with some surrounding tissues. The amount of tissue removed varies according to the nature of the tumour. It is a form of breast-conserving surgery. It is also called a partial mastectomy.

Lumpectomy is the first option of treatment for women diagnosed with early-stage breast cancer.

What is the goal of lumpectomy?

Lumpectomy aims to remove the cancerous cells from the breast and at the same time maintaining the appearance of the breast. Studies have proved that for early stage breast cancer, lumpectomy is as effective as mastectomy (complete removal of the breast).

Doctors may recommend lumpectomy to remove precancerous cells as well.

Pre lumpectomy measures-

If you are under any other medication or if you suffer from allergies, inform your doctor. Other pre-surgery measures include-

  Stop taking aspirins or any pain relieving medication

  Your doctor will recommend you to not drink or eat anything 8-12 hours prior to the surgery.

The procedure:

A mammogram and a biopsy reveal the exact location of a tumour. Lumpectomy is performed under general anaesthesia. The surgeon makes a small incision over a tumour to extract the cancerous cells and the surrounding tissues. Sometimes doctors have to perform sentinel lymph node surgery or axillary node dissection.

The surgeon then closes the incisions with sutures. The sutures may dissolve over time or may have to be extracted later by a doctor.

If you have undergone lumpectomy and sentinel node biopsy, you will be discharged on the same day as the surgery as soon as your blood pressure stabilizes.

However, after lumpectomy with axillary node extraction, you may have to stay in the hospital for 2-3 days.

Therapy after lumpectomy

Your oncologist will recommend a follow-up radiation therapy to destroy the mutated cells that may have remained in the area where a tumour had developed. Radiation reduces the risk of breast cancer recurrence.

You might also have to undergo hormone therapy. Some types of breast cancer need female hormones like estrogen and progesterone to grow. Hormone therapy inhibits the development of cancerous cells by not allowing these hormones to reach the cells.

Your doctor will advise you to avoid strenuous physical activities for at least a month after the surgery.

Lumpectomy is a safe surgical procedure that can root out tumours or precancerous cells from the breast without deforming the shape of it.

Breast Lumpectomy - All You Should Know!

Skin cancer is a condition with abnormal and cancerous skin growth. This often develops due to the over exposure of skin to the sun rays. The three main types of skin cancer include basal cell carcinoma, squamous cell carcinoma and melanoma. Skin cancer affects those areas of skin which remains sun-exposed, including ears, neck, chest, scalp, lips, face, hands, arm and legs. It can also develop on those areas of skin that are not exposed to sunlight like beneath toenails or fingernails, on palms and on genital area.

Here are some of the factors which increase your risks of getting skin cancer:

1.Fair complexion: Low levels of the pigment melanin in skin causes fair complexion. Fair- skinned individuals who have a history of hazel or blue eyes, repeated sunburns and people who have red or blond hair are highly susceptible to developing this form of cancer. Less pigment in skin makes an individual more vulnerable to skin damage from harmful UV radiation.
 
2. Excessive sun exposure: Exposure to the sun may lead to the development of skin cancer, if you don't protect your skin by sunscreen and clothing. Tanning beds and lamps may also increase the risk of developing this type of skin cancer.
                                            
3. High-altitude places: The exposure to sunlight is more intense in areas of high altitude and near the equator. Living at higher elevation also makes you more vulnerable to radiation because the sunlight is strongest there.

4. Moles: People with abnormal moles are at a higher risk of developing skin cancer. These moles are irregular in shape and are larger than normal moles.

5. Precancerous skin lesions: Your risk of developing skin cancer increases if you have skin lesion. These are scaly and rough patches that range from brown to dark pink in color. The most commonly affected areas are head, hands and face of fair-skinned people.

6. Weak immune system: Weak immune system caused by HIV or AIDS and immunosuppressant drugs that you take after an organ transplant may increase your risk of developing skin cancer.

Know If You Are At Risk Of Skin Cancer

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!

Skin cancer most often develops on skin that has faced sun exposure. At the same time, it can also affect skin areas that haven't been exposed to sun's rays. Do you know, skin cancer can be prevented by consuming some foods? Yes, and there are some out there:

1. Fatty fish - Including fatty fish in your diet can shield you against melanoma as they contain the beneficial nutrient Omega-3 fatty acids. In fact, these kinds of fatty acids are considered to be best for consumption as unlike saturated fats, they don't increase your risk for certain types of cancer. A study in the International Journal of Epidemiology reveals that individuals who consume a diet containing fish that is high in these healthy fats have low rates of this form of cancer.
2. Vegetables - This is another food option that is known to possess strong skin cancer-fighting properties. Dark leafy veggies like spinach, kale and broccoli can aid fighting against melanoma. A pigment found in tomatoes called lycopene has properties that guard you against cardiovascular diseases as well as cancers of all kinds. Similarly, the pigment carotenoids found in vegetables like carrots, sweet potatoes, etc are known to protect against sunburn.
3. Herbs - Including herbs in your diet can help in replenishing the minerals and vitamins that get depleted due to the action of the sun. According to experts, about 80% of your body's vitamin levels see a reduction when you stay under the sun for 30-45 minutes. Basil, parsley, and rosemary are a few of the herbs that possess cancer-fighting qualities.
4. Flaxseeds - The unique qualities of flaxseed make it the best option against skin cancer. It contains both antioxidants and omega 3 fatty acids, making it an all-around solution to fighting skin cancer.
