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

Science has advanced a lot through the ages. Doctors have also succeeded in curing many diseases in this time. But even with one of the most advanced technologies, they still haven t found a fool proof way to cure cancer. Even out of the many types of cancer, blood cancer is the worst among them. You surely wouldn t want to get into such a situation. Would you? The best way out of blood cancer is never to get one. To prevent it you can take care of a few things:

Maintaining proper body weight: Although you can t do much to prevent cancer, you must ensure that you maintain a healthy body weight. This implied that your BMI should be normal (healthy weight) so that you have a good chance of fighting it. It has been said by many leading institutions worldwide as the best way to prevent cancer. One can maintain proper body weight by making sure they exercise every day for at least 30 minutes and also maintain a well-balanced diet. This would help you maintain a healthy body weight.
Reduction in the consumption of calorie dense food: Not only because calorie dense foods like cold drinks increase your weight, the sugar mixes with your blood and thus is difficult to transport through the body. Thus they add a lot of impurities to the body and must be avoided for the best interests in your effort to fight cancer. The worst fact about calorie dense foods is that you can easily consume 1000   2000 calories long before you can satisfy your hunger. Thus, it also defeats your first preventive measure to avoid cancer.
Staying away from harmful chemicals like pesticides: You might not know it and be happily spraying pest control sprays everywhere without a proper mask thinking you will make the pests go away. What you don t know is that those pesticides are harmful for your blood and one should avoid them. To increase the probability of winning against blood cancer, it s vital to keep this in mind.
Consulting a doctor from time to time: One should always go and visit a medical practitioner from time to time so that they can maintain proper health. Furthermore, if you see symptoms like fever, frequent infections, night sweating, swollen liver with abdomen pain, enlarged lymph nodes (they are usually painless), then be sure to go to a medical practitioner. Always remember that prevention is better than cure. Thus one should try to prevent blood cancer not cure it.

Blood Cancer - How To Prevent It? 

Fibroadenomas are benign non carcinogenic tumors that occur in the breasts of women. Although the condition may affect females of any age; spanning from pubescent girls to middle aged ladies, yet it is most commonly diagnosed in young women below 30 years of age. Fibroadenomas can be described as a stiff, smooth, supple marble under the skin of your breasts, which move when touched. These tumors which occur in varied sizes, may shrink or expand with time. Diagnosing through biopsies and treatment by surgeries are commonly employed for such a condition.

Types of fibroadenomas
Fibroadenomas are of two types: simple fibroadenomas and complex fibroadenomas. The simple tumors are usually harmless and almost look the same under the lens of a microscope. On the other hand, the complex tumors are comprised of macro cysts (large fluid-filled sacs) and calcifications (deposits of calcium) which can slightly increase the chance of breast cancer.

What is the primary cause of fibroadenomas?
Doctors aren't able to pinpoint the chief cause of fibroadenomas, but they have reasons to believe that the condition may pertain to the reproductive hormones. The condition may occur during pregnancy or during the use of hormone therapy, owing to which, the tumors may increase in size. The tumors are usually seen to shrink postmenopause, when the hormone levels start to dwindle.

Fibroadenomas are apparent and you may be able to detect them even without a doctor. The marble like tumor within your breasts are usually:
1) painless
2) firm
3) rubbery and elastic
4) easily movable

These tumors can range from being too small to as big as 3 inches or more in diameter. These lumps, which are usually harmless may be a cause of concern if they start to grow or change. Consulting a doctor is duly advised in such cases.

Risks
Fibroadenomas, only in the rarest cases, increase the likelihood of breast cancer. A complex fibroadenoma comprising of cysts or thick tissues called calcifications may aggravate your condition. Causes of concern could be if the tumor pains, a family history of cancer or an event of a questionable biopsy report.

Causes and Symptoms of Fibroadenomas

Pulmonary diseases are some of the most commonly experienced health conditions all over the world. Millions of people suffer due to various causes including genetics, smoking, pollutants and infection. Now lungs are one of the most important and complex organs of the body. They are the apparatus through which oxygen enters and carbon dioxide gets expelled. 

Lungs expand and contract on a constant basis to ensure that we can breathe properly. Let us find out more about lung or pulmonary diseases.

Asthma: This is one of the most common and potentially fatal conditions that affect children and adults. It grips the airways formed by the bronchi which branch off into smaller tubes from the main trachea that holds them. This condition causes inflammation, and even spasms, which can lead to wheezing and breathlessness. The main triggers of asthma attacks include allergies, infections and pollutants that may escape into the airways.
COPD: This is also known as Chronic Obstructive Pulmonary Disorder. It is an umbrella term used for various lung conditions that cause breathing difficulties due to an obstruction of the airways. Chronic bronchitis is one of the conditions that falls under COPD, and is usually characterised by persistent, hacking coughs.
Cystic Fibrosis: This is another condition that affects the airways by causing poor passage of mucus from the bronchial tubes. This condition is a genetic one where the mucus that gathers eventually becomes a lung infection.
Pneumonia: This is a condition that causes an infection in the alveoli, which are the tiny tubes that the airways branch into. These are air sacs that can catch myriad infections like pneumonia.
Tuberculosis: This is also a kind of pneumonia, which is caused by bacteria called Mycobacterium Tuberculosis. This condition usually attacks the air sacs of the lungs and can be a potentially fatal disease if it is not treated on time. The patient will require immediate hospitalisation.
Pulmonary Edema: This condition is caused by fluid leaks from the tiny blood vessels into the surrounding air sacs within the lungs. It can also be caused due to heart failure as well as back pressure which falls on the lungs. Direct injury to the lungs can also lead to this condition.
Lung Cancer: This is a fatal disease which can be found in any part of the lungs. It has many forms and the type as well as the location usually determines the kind of treatment option that will be followed.
Acute Respiratory Distress Syndrome: When the lungs suffer a sudden injury which is usually caused by a bout of serious illness, it is called ARDS. Treatment involves the use of life support ventilation.

All About Pulmonary Diseases


Feeling a lump on your breasts can be a terrifying moment. 'Cancer' is the first thing that comes to mind but in reality, most lumps in the breast are not caused by cancer. Apart from cancer, breast lumps can be caused by non-cancerous growths, injuries and infections. The only way to correctly diagnose the cause of a lump in the beasts is through a biopsy. Hence, this is the first step towards treating a breast lump. From here on, treatment will depend on the cause identified.

Mastitis or Breast Infection

Mastitis is a painful infection of the breast tissue often faced by women who are breastfeeding. It can be treated with heat treatment and antibiotics. Massaging the breast while taking a warm shower or applying a warm compress. This will open up the milk ducts and should be followed by nursing the baby or using a breast pump to relieve the swelling and pain.

Abscess

Antibiotics are the first line of treatment against an abscess but this is effective only if given in the initial stage of the infection. In later stages, an abscess will need to be surgically drained.

Fibroadenomas

This is a non-cancerous tumour often found in young women. It is often difficult to distinguish between a Fibroadenoma and a cancerous tumour and hence these are usually surgically removed.

Fibrocystic Changes

In some cases, the breast itself is composed of knotted, rope like tissue. This is known as having fibrocystic breasts. If a new lump presents itself on fibrocystic breasts, a mammogram and an ultrasound are performed to evaluate the lump. In most cases fibrocystic changes do not require any medication or surgery.

Breasts Cysts

Cysts can be defined as fluid filled lumps. In some cases, these cysts become apparent at the time of ovulation and disappear after the period. In other cases, it may need to be drained with a thin needle. Cysts often recur and need to be re-drained.

Fat Necrosis and Lipoma

Fat necrosis is a lump caused by an injury to the fatty tissue in the breast. Lipoma is a fatty growth within the fatty tissue. In both these cases, no treatment is required but if it causes any problems, it can be removed.

Breast Cancer

If the biopsy reveals the presence of a cancerous tumour, you must immediately consult an oncologist. Treatment options for breast cancer include chemotherapy, radiation, surgery and hormone treatment.

Treating Lumps and Pain in Breasts of Women

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.
