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
- 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.

Many women develop uterine fibroids by the time they hit the age of 50 years and above. These are non-cancerous growths that may occur in the uterus. Most women go through severe bleeding and pain as well as discomfort as a result of these fibroids. Age, family history of the same condition, obesity or being overweight, eating habits and even ethnicity play a large role in deciding the risk of each individual patient. These fibroids can grow in the submucosal, intramural and subserosal areas.
Following are the common side effects of uterine fibroids:
- Frequent urination: Due to the pressure of the fibroids on the uterus, the patient may experience a constant feeling of fullness in the lower pelvic area of the body, which may lead to frequent filling of the bladder. This gives rise to frequent trips to the washroom for urination.
- Heavy Bleeding: Severe bleeding is one of the most common causes of the presence of these kinds of fibroids. The patient may experience a lot of bleeding during menstrual periods, as well as pain and cramps the rest of the time. The periods will also be very painful when there are fibroids in the uterus or the uterine lining.
- Painful Intercourse: It is a well-known fact that any kind of infection or growth as well as sores and other such ailments can lead to vaginal dryness as well as pain during sexual intercourse. This is true for uterine fibroids as well, which can lead to severe pain during sexual activity. These fibroids can also give rise to pain in the lumbar or lower back region.
- Abdomen Swelling: The abdomen may go through significant swelling in such a condition and the patient may even look like she is pregnant. The growth can push the shape of the abdomen outwards and create a full feeling.
- Pregnancy Complications: The presence of uterine fibroids can give rise to several complications during pregnancy and even after child birth. One of the most common problems in this case is bleeding, followed by more severe outcomes like miscarriage. The women suffering from uterine fibroids are at greater risk of undergoing a caesarean section for the delivery of the baby. The baby may also be born breech and a premature delivery may take place.
- Infertility: This is also a rare side effect of the uterine fibroids and is generally seen only in very severe cases.
- Cancer: Only one in every 1000 cases might transform into malignant tumours. These uterine fibroids are generally known to be non-malignant.
Any symptoms must be reported to a gynaecologist at the earliest to avoid any serious complications.

Breast cancer is the form of cancer that occurs from breast tissues in women. Signs of breast cancer may include a lump in the breast, changes in the shape of the breast, dimpling of the breast skin, a fluid coming out of the nipples or development of red scaly patches on the skin. There might be pain in the bones, swollen lymph nodes, shortness of breath, or the skin turning yellow and pale.
Breast cancer is a fatal mode of cancer in women, and one must try to abstain from this cancer in all possible ways. Here are 5 ways you can decrease the risk of breast cancer.
- Keeping a check on your weight: Although the process is tough to maintain, keeping up a sound and healthy weight is a critical objective for everybody. Being overweight can expand the danger of a wide range of cancers, including breast cancer, particularly after menopause in women. Exercise is very important for maintaining a healthy body and lifestyle. Women who exert physically regularly are fitter than others and are at a much lower risk of acquiring diseases of any kind. Regular exercise decreases the chance of getting breast cancer and also keeps the body weight in check.
- Maintaining a healthy diet: Maintaining a healthy and balanced diet is a key for keeping away from any kind of cancer or major health problem. Include a sufficient amount of fresh fruits and green vegetables in your daily diet to ensure the supply of all vital nutrients to your body. This would increase your immunity.

Heart diseases, stroke and many kinds of cancer, including breast cancer can be caused from smoking. If you drink alcohol, you should moderate your drinking habits and drink less, as drinking in excess may lead to breast cancer.
- Practice breast feeding: Breast feeding your children for a span of one year or more is likely to reduce the risk of breast cancer.
- Avoid taking birth control pills: Birth control pills, in spite of having several benefits are associated with risk factors as well. Birth control pills have got worse effects in younger women than older aged women. Using birth control pills may cause breast cancer and these pills should be avoided.
There are many ways, adapting which you can lower the chances of getting breast cancer.

Breast Cancer - What exactly is it?
‘Breast cancer’ is a term that is used to refer to a malignant tumour, which has developed from cells present in the breast. Generally, all tumours can be divided into two categories i.e. benign and malignant and it is the malignant tumour that is responsible for causing cancer. Breast cancer generally originates in the cells the milk producing glands of the breast's or the passage, which carries milk from the glands to the lobules. Additionally, breast cancer can also originate in the stromal tissues, including the fibrous and fatty connective breast tissues.
Breast Cancer: Treatment Options
Treatment for breast cancer depends upon two things: the exact type of the cancer and how advanced the cancer is. Treatment options for breast cancer can thus be broadly divided into two categories as Local treatments and Systemic treatments.
Treatments that target the tumour without having any effect on the rest of the body are called local treatments. The following types of local treatment options are available for treating breast cancer:
- Surgery: Surgical breast cancer treatment involves removal of the malignant cancerous tumour in an operation. Smaller tumours can be removed using a surgical process referred to as ‘lumpectomy’, wherein the tumour along with a small amount of healthy tissue surrounding the tumour is removed. For larger tumours, removal of the entire breast becomes mandatory, in a surgical process known as ‘mastectomy’. Women who undergo mastectomy can choose to undergo reconstructive plastic surgery for reconstruction of the removed breast(s).
- Radiation Therapy: This basically involves using radiation to kill cancer cells present in the body. Radiation therapy is a long-drawn process that usually involves a set number of treatments administered over a long period of time. Radiation therapy is also generally the follow-up procedure after a lumpectomy, or more rarely, a mastectomy.
Treatments involving drugs that are administered via either the mouth or direct injection into the bloodstream are called systemic treatments. These include:
- Chemotherapy: This includes using drugs to destroy the cancer cells present in the body by stopping the cancer cells from growing and dividing. Chemotherapy can be administered using either an IV (intravenous) tube or via pills that can be swallowed.
- Hormone Therapy: This treatment option is used for treating tumours which have tested positive for progesterone or oestrogen receptors. Blocking hormones that fuel the tumour’s growth is the basis of this therapy.
- Targeted Therapy: This targets specific proteins and genes which contribute to growth and survival of the cancer cells. Targeted therapy is an extremely focused treatment, and is very effective in blocking the growth and division of cancer cells, as well as minimizing damage to surrounding healthy cells.
My mother is suffering from disc extrusion in L5, is surgery necessary? Or something other will be helpful.
Our spinal disk resembles a jelly donut, wherein the softer insides are protected by the hard exterior. Sometimes, as a result of some injury or an accident the jelly slips out, leading to an extremely painful condition which in medical parlance is known as herniated disc. The pain that you are subjected to, during herniated disc, occurs as the nerves nearby are damaged due to the concussion.
Apart from pain, herniated disc is preceded by other symptoms, some of them are:
- Pain in the arm or the leg: Depending on which part of the body you have suffered the herniated disc, in the neck or in your lower back, this condition is succeeded by intense pain either near the buttocks or near the shoulders. It goes without saying that this pain increases sharply with movement.
- Numbness: That part of the body where the nerves are damaged due to herniated disc often becomes numb and has no sensation whatsoever.
- Weakness: Due to herniated disc, the muscles become weak that considerably impairs and curbs mobility.
However, there are various ways by which you can prevent a herniated disc. Some of them are:
- Exercise: Exercise in any form and even for a short while yields several benefits. Your body invariably gains momentum and agility. If you exercise daily, your spine becomes more stable and strong, thereby preventing a possible herniated disc.
- Maintaining the right and good posture: A lot depends on the way you sit and walk, in fact more than you can imagine. If you sit badly, it exerts a pressure on the spine and the discs. Subsequently, a good posture does the very reverse and curbs chances of a herniated disc in the future.
- Keep a tab on the weight: It is always healthy to maintain the right weight, the one that keeps you away from the onset of various diseases. If you are overweight, it puts more pressure on the spine disk, thereby increasing the risk of developing a herniated disc.
