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.

Cerebral ischaemia or brain ischemia is a medical condition that restricts the flow of blood to the brain, resulting in an unmet metabolic demand. This leads to limited oxygen supply in the brain, which could result in death of brain tissues, cerebral infarction or an ischemic stroke. Thus, a cardiorespiratory arrest, a stroke, and irreversible brain damage are few possible consequences of cerebral ischaemia.
People with compressed blood vessels, low blood pressure, congenital heart defects or sickle cell anaemia have a high risk of developing cerebral ischaemia, since compressed blood vessels or very low pressure can lead to restricted blood flow. Also, sickle-shaped cells have a greater tendency to clot, causing obstructed blood flow.
Patients with cerebral ischaemia experience a host of symptoms, such as weakness in the body, problems in coordination and movement, vision and speech impairment and unconsciousness.
Cerebral congestion, on the other hand, refers to excessive quantity of blood in the brain vessels, causing pressure on the cerebral substance. Cerebral congestion is of two types. It is termed as active when there is too much arterial blood flow and passive when there is undue quantity of venous blood in the veins of the brain. Both conditions cause symptoms, such as severe headache, insomnia, irritability and unconsciousness. The patient gets little sleep and is disturbed, often followed by dreams. When awake, the patient’s mental activity in the brain is very high.
Homeopathy is now a well-established school of medicine backed with years of research and practice. Gone are the days when homeopathy was considered no more than an extension of herbal home remedies. Homeopathic laboratories around the world produce large number of medicines covering almost all ailments. The benefits of homeopathic treatment are now well established due to its holistic approach and minimal side effects. Homeopathy is undoubtedly a ray of hope for patients with cerebral ischaemia and cerebral congestion, as it delivers a comprehensive treatment plan designed to target the signs and symptoms of the disease and address its non-occurrence.
The medications deal with mild to severe symptoms, including inflammation of the brain, headache, vomiting, insomnia, stroke/convulsions and seizures. The stramonium drug, for example, deals with seizures. Belladonna is an effective remedy for sharp shooting headaches, a common symptom of cerebral congestion. Ferrum is believed to be a valuable remedy for brain ischaemia. Few drugs deal with the symptoms of both ischaemia and congestion—nux is a suitable drug for the treatment of ischaemia as well as for passive cerebral congestion. Similarly, phosphorus can be used to treat brain ischaemia and congestion. Zincum metallicum is a highly recommended drug for chronic cases of ischaemia.
The treatment is comprehensive and long term and shows substantive results. Regular follow-ups and consultation with a homeopath specialist is the key to an effective treatment.
Uterine cancer is also known as endometrial cancer. It is a cancer which begins in the lining of the uterus. The uterus is the part of a woman's body where the fetus develops. Uterine cancer is one of those rare cancers in India, which can be diagnosed in its early stages. This is because excessive vaginal bleeding occurs, thus making it a very serious and an apparent symptom. It is also one of the few forms of cancer which can be cured as removing the uterus is often more than enough to cure the patient of uterine cancer.
Here are the causes, diagnosis and treatment of uterine cancer:
The exact cause of uterine cancer is not yet known, however, there is a theory on what causes uterine cancer. Hormones in a woman's body have been thought to increase the chances of getting uterine cancer. This is because it has long been thought that having high levels of estrogen is the cause of uterine cancer. Increased estrogen thickens the endometrium and thus, increases the likelihood of uterine cancer.
1. Pelvic exam: This is an examination in which the vagina, bladder, rectum and uterus are scanned for lumps. If they are found, it might be due to uterine cancer.
2. Pap test: A pap test is a special test designed to scan for uterine cancer.
3. Transvaginal ultrasound: A transvaginal ultrasound uses high-intensity sound waves so that pictures of the uterus can be taken.
4. Biopsy: During a biopsy, the doctor will remove tissue from the endometrium and it will then be analyzed for cancerous growths.
1. Surgery: This is the most common treatment as it removes the entire uterus and prevents the spreading of the cancer.
2. Chemotherapy: Chemotherapy involves giving drugs which kill cancerous cells. They are given through either an intravenous line or even in pill form.
3. Hormone therapy: This is a therapy in which either progesterone levels are increased or estrogen levels are decreased.
4. Radiation therapy: In this treatment, high energy laser beams are used to destroy cancerous cells. If you wish to discuss about any specific problem, you can consult a Gynaecologist.
A broken bone or a fracture can be painful and it requires medical attention for the fracture to heal properly. Proper healing is necessary for the right alignment of the bone. A doctor chooses to either reduce or set the bone in terms of new alignment. The bone reduction can happen manually or surgically depending on the severity of the injury. A Surgical procedure known as the open reduction internal fixation is performed for serious fractures. It ensures that the all the broken pieces are fixed together and the injury can heal properly.
Post the fracture, the bone need to be immobilised for proper healing. This is generally achieved by imposing a cast. For fractures that are not severe in nature, a doctor might choose to impose a temporary cast so that simple motion can happen around the site of the injury. For serious fractures, a permanent cast is placed around the injury site. In the case of a shoulder injury, a patient is required to wear a sling so that the bones are immobilised.
Time Duration of a Therapy Session:
While the exact duration of physiotherapy can vary from individual to individual, it takes a minimum of 2-8 weeks for the fracture to completely heal. Certain fractures take more time to heal. The rate of healing also depends on the severity of the injury, pain threshold level of the patient, extent of work with the physiotherapist, the robustness of the physiotherapy program, extent of the injury of the soft tissue and certain other factors. Typically shoulder and neck injuries heal quicker than a fracture of the legs. The time duration of fracture healing also depends on the type of bone that has been affected.
Physiotherapy in a Hospital:
If the fracture happens in the ankle or leg, a physiotherapist might have to intervene in the hospital in order to teach patient about using assistive devices such as crutches and cane. Things that are taught during this time include using the device in order to climb stairs, right walking posture, getting into a car, taking the device off while sitting and such other techniques.
Physiotherapy at Home:
Physiotherapy can also happen from home if the doctor specifically instructs to do the same. This is typically done for people where the condition is too serious to go outside and get the physiotherapy done. Certain weight bearing restrictions are imposed around this time. The training remains the same as in the case with a hospital.
In the Clinic:
Once the patient becomes mobile enough, a doctor might suggest a patient go to a clinic to get the physiotherapy done. A physiotherapist evaluates certain things such as pain, range of motion, gait, flexibility etc. of the patient before suggesting a certain exercise plan. If you wish to discuss any specific problem, you can consult a physiotherapist.
Breast cancer is an abnormal growth of cells in the tissues of the breast. Mainly it occurs in females but less than 1% of all the breast cancer cases develop in males. The majority of breast cancers start in the milk ducts. A small number start in the milk sacs or lobules. It can spread to the lymph nodes and to the other parts of the body such as bones, liver, lungs and to the brain.
With more reliable early detection methods as well as the trend towards less invasive surgery, there is hope that even more women with breast cancer will be treated successfully and will go on to resume their normal lives.
Signs & Symptoms
It is painless, especially, during the early stage. Watch out for the following changes in the breast:
- A persistent lump or thickening in the breast or in the axilla.
- A change in the size or shape of the breast.
- A change in the colour or appearance of the skin of the breast such as redness, puckering or dimpling.
- Bloody discharge from the nipple.
- A change in the nipple or areola such as scaliness, persistent rash or nipple retraction (nipple pulled into the breast).
Consult a doctor immediately if you notice any of these changes.
Being a woman puts you at risk of getting breast cancer. There are certain factors that increase the risk of breast cancer. Some of them have been listed below:
- The risk increases with age; most cases of breast cancer develop after the age of 50
- Genetic alterations in certain genes such as BRCA1 and BRCA2
- Family history of breast cancer
- Being overweight
- Early menarche (onset of menstruation before the age of 12)
- Late menopause (after the age of 55)
- Never had children
- Late childbearing
- No breast feeding
- Excessive consumption of alcohol
- Use of hormonal replacement therapy (HRT) for a long period of time
However, most women who have breast cancer have none of the above risk factors. Likewise, not having any of these risk factors does not mean that you will not get breast cancer.
Early Detection and Screening
More treatment options are available when breast cancer is diagnosed at an early stage and hence the chances of recovery is also higher. So regular breast screening is important for early detection even if there are no symptoms. Following are the ways of screening:
- Breast Self-Examination (BSE): Perform BSE once a month about a week after your menses are over. If you no longer menstruate, choose a date each month which is easy to remember e.g. your date of birth or anniversary.
- Clinical Breast Examination: Get a breast specialist to examine your breast once a year if you are 40 years and above.
- Mammogram: Go for a screening mammogram once a year if you are 40 to 49 years old and once every two years if you are 50 years and above even if you do not have any symptom. It is not recommended for younger women (less than 40 years of age) as they have dense breasts, making it difficult for small changes to be detected on a mammogram. So ultrasonography of the breasts is advisable to them.
Types of Breast cancer
- Non-Invasive Breast cancer: These are confined to the ducts within the breasts. They are known as Ductal carcinoma in-situ (DCIS).
- Invasive Breast cancer: It occurs when cancer cells spread beyond the ducts or lobules. Cancer cells first spread to the surrounding breast tissue and subsequently to the lymph nodes in the armpit (Axillary lymph nodes). These cells can also travel to the other parts of the body such as bones, liver, lungs or brain and hence known as metastatic breast cancer.
Making A Diagnosis
If you notice any unusual changes in your breasts, you should see a doctor immediately. He will examine you clinically and may ask you to undergo some tests so that a definitive diagnosis can be made. Further, the staging work up is done to find out the stage of the disease and management accordingly.
Treatment of breast cancer may include various methods such as surgery with or without breast reconstruction, chemotherapy, radiation therapy, hormonal therapy and targeted therapy. Treatment options offered, depend upon the number of factors such as the stage of cancer and likelihood of cure, your general health and your preference. In case you have a concern or query you can always consult an expert & get answers to your questions!
If you are concerned about breast cancer, you should know about the steps you can take to prevent the condition. Breast cancer is a type of cancer developing from the breast tissue. Symptoms such as a lump in the breast, fluid flowing from the nipple, changes in the shape of the breast and occurrence of red scaly patches on the breast denote breast cancer.
You need to make certain lifestyle changes in order to prevent breast cancer. The ways you should adopt include the following:
Limit your alcohol intake: The more you consume alcohol, the more you put yourself at the risk of getting breast cancer. It is recommended for you not to drink more than one drink per day. Small amounts of alcohol increase the risk of breast cancer as well.
Abstain from smoking: There is a direct link between tobacco smoking and breast cancer, and the risk is even more in premenopausal women. You should quit smoking to reduce the risk of breast cancer along with many other conditions, which can develop because of the ill-effects of smoking.
Control your weight: Obese women are more prone to breast cancer when compared with women with a healthy weight. This is especially true when obesity occurs at a later stage in life, after menopause.
Keep physically active: Regular physical activity is essential for you to maintain a healthy weight, which is important for preventing breast cancer. 150 minutes of moderate aerobic exercises or 75 minutes of vigorous exercises are recommended along with strength training.
Breastfeed: Breastfeeding plays an important role in preventing breast cancer. The more you breastfeed your baby, the more protected you are from breast cancer.
Limit the dosage and duration of hormone therapy: If you undertake combination hormone therapy for more than three to five years, you are at a higher risk of developing breast cancer. In case you are taking hormone therapy for menopausal symptoms, you should talk to your doctor about alternative options such as non-hormonal therapy and medications. If you still require hormonal therapy, you must use the lowest dose that will be effective.
Avoid exposure to radiation and pollution: Certain medical imaging procedures like computerized tomography involves radiation of high doses. There is a link between breast cancer and radiation exposure. Thus, you should abstain from getting exposed to radiation and avoid taking such tests if it is not very urgent.
Maintaining a healthy diet also helps in reducing your risk of developing breast cancer. You should include food items which are plant based in your regular diet, such as fruits, vegetables, nuts, whole grains and legumes. Also, consume healthy fats such as olive oil instead of red meat and butter. If you wish to discuss any specific problem, you can consult an oncologist.
