Lung cancer is caused by disorderly growth of uncommon cells which line the air passage, usually starting off in a single or both lungs. The irregular cells do not mature into healthy lung tissue but instead divide speedily and result in tumor formation.

Causes behind lung cancer:

Smoking: This is considered as the most significant source of lung cancer. As reported by multiple researches and studies, cigarettes contain over 4,000 chemicals, most of which are cancer causing agents. Active smoking is one of the major causes of lung cancer but what may come to you as a surprise is that extended periods of passive smoking is also a major factor.
Pollution and Exposure: There is high risk of lung cancer development when there is occupational exposure to pollution by chemicals released from industrial factories. Chemical exposure of this kind refers to prolonged exposure over quite few months or years. Some examples of these chemicals are asbestos, diesel exhaust among many others.
Radioactive Gas: Radioactive gases naturally occur in small masses present in all soils and rocks. However, if you breathe in radioactive gases your lungs will damage and may cause the development of abnormal tissue which can cause lung cancer.
Family history: A family history of cancer, especially lung cancer will also put you at high risk of developing lung cancer.
Treatment methods of lung cancer:

Chemotherapy: Chemotherapy is a method in which drugs are injected through veins in your arm (intravenously) or orally or in a combination of both. These drugs kill cancer cells and help to stop it from spreading any further as well.
Clinical Trials: These trials are experimental lung cancer treatment studies. You may have to try out this clinical therapy if other treatment methods aren t working and only if you are accepted into it.
Surgery: A surgeon will help remove affected areas of the lung including cancerous tumors via surgery. The surgeon may need to remove parts of the lung along with the cancerous growth. In certain cases, one side of the lung may also be completely removed to stop the spread of the malignant tissue.
Radiation Therapy: This is a therapy where high energy electromagnetic waves are passed through your body to destroy cancer cells with the help of high-powered energy beams.
Can you prevent lung cancer?

Nutrition -- A  healthy diet with lots of fruits and vegetables may also help reduce your risk of lung cancer. Some evidence suggests that a diet high in fruits and vegetables may help protect against lung cancer in both smokers and non-smokers. But any positive effect of fruits and vegetables on lung cancer risk would be much less than the increased risk from smoking.
Exercise -- Even moderate amounts of exercise can aid in lung cancer prevention. Studies suggest that even something as simple as gardening twice a week is associated with a lower risk of developing lung cancer.
Smoking Habits -- If you stop smoking before a cancer develops, your damaged lung tissue gradually starts to repair itself. No matter what your age or how long you ve smoked, quitting may lower your risk of lung cancer and help you live longer. 
Avoidance of Air Pollution -- Long-term exposure to ambient air pollution and, in particular, particulate matter with absorbed polycyclic aromatic hydrocarbons and other genotoxic chemicals has been suspected to increase the risk for lung cancer. So, avoid air pollution as much as possible.

Lung Cancer - Ways You Can Prevent It!

One of the most common issues with old age in men is the enlarged prostate. Any difficulty with urination (no constant stream, difficulty initiating, or incomplete emptying of the bladder for instance), and the first suspect is an enlarged prostate. These symptoms are followed by a digital rectal exam to check for an enlarged prostate. Once confirmed, the next step is to check for levels of prostate-specific antigen (PSA). If both the exam and the PSA are positive, it could mean prostate cancer. As with any cancer, it is believed that sooner it is diagnosed and the treatment is started, the better.

Historically, the best way to rule out the prostate cancer had been to do a prostate biopsy. This is a minor invasive procedure, wherein biopsies are taken from various regions of the prostate which are known to develop cancer (about 12). A disadvantage of this procedure includes missing out on the front part of the prostate which can also develop cancer. Secondly, it is not a very pleasant experience and given a chance, most men would not want to have it done.

There is good news for these men who would like to avoid prostate biopsies. The first is the multiparametric MRI which uses no x-rays and is considered very safe with extremely accurate results. This MRI exam requires about an hour, and once the images are obtained, the doctor will analyse these images and check for several parameters to assess for prostate cancer. The absence of cancer can be confirmed with up to 90% accuracy, which is far greater than with usual biopsies. If there is a possibility of cancer, then a biopsy can be done to confirm it. 

Also, these images indicate the exact region where cancer likely is, and this guides the doctor to biopsy only where absolutely essential. The chances of false positive and false negative results are reduced drastically. The one disadvantage here is that MRI detected biopsies usually tend to be of a higher grade which requires immediate treatment.

Another way to reduce chances of the biopsy by 30% to 50% is by the 4K test. It helps detect a variety of prostate issues including cancer. It can be used once higher levels of PSA is identified and before going for a biopsy. It combined 4 prostate-specific biomarkers with clinical information to accurately provide men with a risk of developing prostate cancer. It can be used even after negative biopsies to confirm the diagnosis of prostate cancer.

These two measures can drastically reduce the incidence of prostate biopsies, which is neither pleasant for the patient nor very effective for the doctor.

Skin cancer is a condition with abnormal and cancerous skin growths. This often develops due to the overexposure of skin to the rays of the sun. 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 the genital area.

Risk factors associated with skin cancer

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.

Skin Cancer - What Can Cause It?

Developing cancer is either totally your bad luck where you haven t been doing anything wrong in your diet and lifestyle still develop it or it is out of bad lifestyle, eating habits and negative attitude towards life. But death due to cancer is totally due to carelessness in which a person didn t pay attention to initial symptoms and left cancer for thriving in the body. The truth has been said that cancer isn t a killer but delayed diagnosis and wrong or improper treatment is. Awareness, early diagnosis and treatment is the key to survival. Cancer does not always mean death if some earlier signs of cancer are noted and action is taken timely.

In normal conditions our body functions normally, i.e. we eat, pass urine and stool, breath, and drink water. Any alteration from this is abnormal and must be noticed like difficulty in swallowing, difficulty in urinating and defecating, passing blood in urine or stool, long continued severe pain in any part of the body.

The appearance of new moles on the body which keep on growing with an irregular border, painful and bleed.

Hoarseness of voice

Long persisting cough and blood in saliva. Cough lasting more than a month.

Loose stools or any change in bowel habits without any dietary changes lasting more than a few weeks needs to look into.

Presence of blood in stool without any obvious reason like ulcers or hemorrhoids.

Unexplained low blood count, i.e. anemia. Anemia needs to be evaluated unless there is any obvious source of blood loss.

Not all breast lumps are cancerous but all of them should be investigated. Also if there is any bloody discharge or discharge only from one nipple that should also not be ignored at all. Self-examination of the breast daily once a week is necessary and it is easy too. Check for any nodule or discharge from the breast.

Any lump in the testicles should be evaluated thoroughly. Men should also do a self-examination of the testicles, once in a month.

Urinary symptoms like less urine, pain while passing urine, blood or burning in urine, especially in men shouldn t be ignored. It can be a sign of bladder or pelvic cancer

Hoarseness without any respiratory infection or persistent for more than 3-4 weeks.

Normally lymph nodes swell due to any surrounding infection and then shrink eventually when the infection goes away. If it remains for a longer time and without any infection in the body, should be investigated.

A mole that is multicoloured with irregular borders, bleeding can be cancerous. Especially which is growing rapidly and is painful shouldn t be avoided at all.

Long continued heartburn and difficulty in swallowing even after using over the counter antacids. This can be a sign of esophageal cancer.

Bloody discharge or bleeding from the vagina which is unusual or after menopause can be due to cancer of the uterus or cervix.

Unobvious or unexplained weight loss, fever or night sweats can be an early sign of different types of cancer.

Continuous itching in the genital or anal area, non-healing sores and pain in back, head, bloating and indigestion which is there for a long time without any cause, should be inspected.

Cancer can be horrifying and debilitating but if diagnosed early by giving attention to the symptoms mentioned above and treated properly can fight off. Cancer is no more incurable if treated early. In cases where this disease is out of carelessness if some points are kept in mind and followed, prove to be preventive. If not preventive then definitely reduce the risk of developing it at least.

Do not overuse the birth control pills. Using them randomly can increase the chances of cancer.

Excessive consumption of alcohol shouldn t be done as it irritates the gastric mucosa and increases the incidences of malignancy. However, an occasional glass is fine and does no harm.

Avoid using pesticides around you or having things on which they are sprayed as many of them are definitely carcinogen.

Say no to smoking as tobacco in any form is an invitation to death. Smoking for a long time like 10-30 years can make you pay a heavy price for that.

Long continued anxiety and stress create havoc in the hormonal system of the body which ultimately results in diseases. Try to keep yourself more optimistic and relax in daily life.

Prefer organic vegetables and fruits as other ones have pesticides used while growing them which are definitely a source of getting carcinogens in the body.

Limit intake of processed and packaged food as they increase the risk or certain types of cancer. 

Stay active and try to maintain healthy weight.

Cancer can be the biggest slayer of the health but one can fight it and keep it at bay if mentioned tips are read and implement. Early diagnosis can prevent many lives. So spread awareness and let more people know about it. 

Cancer - A Misfortune Or Carelessness!

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!

Melanoma is a condition which mainly indicates a severe malfunction of the melanocytes or the melanin producing cells of the body. These cells are responsible for giving you your skin colour, tone and complexion. Usually, a person suffering from melanoma will have many normal and irregular moles as well as melanoma in the eye and digestive tracts too.

Some general facts on melanoma are mentioned below:
Melanoma is common in young women and causes many deaths.
More than one million new instances of skin cancer or melanoma are analyzed every year.
There has been a 2000% increase in rate of melanoma since the year 1930. One out of fifty get affected by this cancer.
There has been a high rise in the rate of melanoma from 1970 to 2008. There has been an 800% increase in young women and 400% increase in case of similar aged men.
Early recognition makes melanoma treatable. It is screened for growth very minimally.
Primary causes Melanoma may be caused primarily due to these causes:
The most primary cause of melanoma is ultraviolet light (UV) in people with a low level of skin pigment. The UV light might be from either the sun or from different sources, for example, tanning devices. Around 25% of cases occur from or in the form of moles.
The individuals who work on airplanes seem to have an expanded danger, due to more contact with UV rays.
Ultraviolet UV light of wavelengths between 315 - 280 nm from the sun react with the skin cell DNA and result in a kind of direct DNA harm called cyclobutane pyrimidine dimers (CPDs).
In order to stay away or avoid melanoma, you should:
Avoid the sun at peak hours.
Examine your skin at times for some kind of change.
Keep away from tanning salons.Melanoma is a dangerous form of cancer and causes a lot of deaths. You should stay away from anything that causes melanoma.
