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

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!

Lasers have come as a boon to treat many medical conditions very safely and effectively. They are absolutely indispensable for permanent hair removal, tattoo removal, freckle removal, skin rejuvenation, treatment of birthmarks and many other internal medical conditions. There is a common misconception that lasers are harmful for your skin and can cause skin cancers. This is far from the truth, since lasers are actually used to treat skin cancers and also help in keeping the skin youthful and rejuvenated. 

Lasers use non-ionising light (like red or green light) and not ionising radiation like x-rays or gamma rays. These spectrums of light do not induce cancer formation. 
Fair skinned races are at much greater risk than skin of color. Melanin in darker skin does not allow harmful UV light in sunlight to penetrate through and the risk of skin cancers in darker skin is therefore small with normal sun exposure. Also, common lasers do not use UV light. 
Laser treatments are administered not in prolonged durations but in pulses much less than a second and parameters in the range of milliseconds and microseconds are most commonly used. Prolonged sun exposure is the most common precipitating factor for skin cancers. 
Laser light does not reach any internal organ. In fact, it requires some expertise even to make laser light reach its target just 1-2 millimeters below the skin. This is because melanin pigment in skin blocks laser light from getting through. An expert dermatologist with sound knowledge of skin optics and laser physics is able to achieve this safely and effectively. 
Laser treatments work on the principle of ''selective photothermolysis'. This means that laser light very specifically destroys only the intended target. Thus, a hair removal laser will destroy only the hair roots while leaving surrounding skin structures unharmed. Similarly, blood vessels in birth marks, collagen in wrinkles or scars, abnormal growths and cancers and individual inks in tattoos can be targeted very specifically with lasers without affecting any other structure.

Lasers - Do Not Cause Cancers!

A breast lump is a restricted swelling, projection, lump or knot in the breast that doesn't feel like a breast tissue. There are diverse reasons why breast lumps occur.

Not all lumps are cancer. These can also be breast conditions that are not harmful and which can be easily curable.Knots that feel harder or are not the same as the rest of the breast need to be checked. This kind of irregularity might be an indication of breast cancer.

A self-examination should be your starting point. This is how you can detect a lump on your own:

Step 1: Begin by taking a look at your breast in the mirror. Keep your shoulders straight and your arms on your hips.

This is what you need to search for:

    Breasts that are their typical size, shape, and shading
    Breasts that are uniformly formed without distortion or swelling

In the event that you see any of the changes mentioned below, convey them to your doctor:

    Dimpling, puckering, or protruding of the skin
    A nipple that is not in its initial position
    Redness, rash or swelling

Step 2: Now, raise your arms and look for the changes mentioned above.

Step 3: While you're in front of the mirror, search for any indications of liquid or blood discharge from the nipples.

Step 4: Next, examine your breasts while resting.Use Your right hand to feel your left breast and use your left hand to feel your right breast. Cover the whole breast from your collarbone to the highest point of your mid-region, and from your armpit to your cleavage to search for any lumps.

Step 5:Examine your breasts while either standing or sitting. Many women find that the easiest approach to examine their breasts is when their skin is wet, so this step could be done while taking a bath as well.

Diagnosis:

    Mammogram: Mammography is a technique using X-rays to diagnose and locate tumours of the breasts.
    Breast ultrasound: Breast ultrasound utilises sound waves to create pictures of the breasts from the inside.
    Breast MRI:This involves using an effective and attractive field, and radio frequency pulses to create photos of the insides of the breasts.
    Ultrasound-guided biopsy: During this sort of biopsy, utilising ultrasound imaging to discover the bump, a radiologist will give you anesthesia and afterward insert a needle into the lump to evacuate some tissue for assessment under a magnifying lens. Stereotactic biopsy and an X-ray-guided biopsy may also be used.

Possible treatments:

    In case the knot turns out to be cancerous, surgery is typically performed.
    You may have a few discussions with different doctors for additional treatment, including radiation treatment and chemotherapy or hormone treatment.

What You Should Know About Breast Lump Detection

How to become less prone to cancer

There are various known reasons why cancer takes root in a healthy body. The deadly disease takes away millions of lives worldwide and remedies in food to tackle it are constantly a subject of research. However taking this one food item off your daily diet can help becoming less prone to cancer.

Senior cancer experts stress that sugar feeds cancer. According to his belief, backed by years of research and medical expertise, it is possible to starve cancer out of a person’s body. When sugar breaks down in the body in a non-oxidative manner, adenosine triphosphate (ATP) is generated which causes cancer cells and tumor to grow.

Research states that cancer is a dysfunction of the mitochondria caused by fermentation of sugar in the cells instead of orthodox respiration of normal cells. This can be tackled by limiting the supply, just by cutting down the intake of sugar every day. A small amount of sugar in a healthy and requisite proportion is acceptable but excessive sugar must be avoided in order to choke cancer out from the body.

Specifically, the intake of sugar in processed foods must be cut down. Everything that is sweet isn't sugar! Avoiding processed foods will simply eliminate the bad salts and bad sugars from your diet. Eating at fast food joints too must be cut down completely as the food they serve is frozen and needs a lot of preservatives. You can always switch to fruits if you have a sweet tooth. Diet-wise, consume more green leafy vegetables, developing a plant and natural nutrient based diet is an ideal method to tackle cancer.
