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

One of the most significant glands in the male reproductive system is the prostate gland, which is responsible for carrying urine from the bladder. It is located right under the bladder and helps in production of semen which contains sperm.
Prostate cancer is a slow growing form of cancer that is rarely seen in men below the age of 50. It may occur due to both, genetic and environmental factors. Here is a list of measures that can help in preventing this ailment.
Food Intake and Weight: Apart from age, the major factor that contributes to the risk of prostate cancer includes food and weight. Doctors suggest that bringing down your intake of calcium and fat that comes from red meat and excess dairy can help in preventing the onset of this ailment. The calcium intake should not go beyond 1,500 mg per day, which is why doctors will usually ask you not to have supplements. Cooked tomatoes with olive oil as well as cruciferous vegetables including broccoli and cauliflower should be included as a vital part of one's diet, while fish should be taken regularly as it is a source of healthy or good fat like Omega-3 fatty acids. In general, you should have fewer calories which should be matched up with ample exercise so that a healthy weight and balance is maintained.
Stress and Blood Pressure: Stress and anxiety are also major reasons that contribute to the onset of this disease. One will need to see a doctor about high blood pressure, especially the kind that is triggered by stress and causes hypertension. Also, you must control your cholesterol and stay out of depression to ensure that your risk of developing prostate cancer reduces. Also, having these conditions along with prostate cancer makes the survival chances that much lower. So, you must get the right medication and treatment for these conditions as well.
Lifestyle: One will need to quit smoking, that can cause a number of ailments including prostate cancer. Also, drinking alcohol in moderation is required in order to have a healthier lifestyle and cut the chances of developing such ailments.
Screening: While your diet and other aspects may be right, there is still a great chance of developing prostate cancer, especially if anyone in your family has been afflicted with this condition in the past. Therefore, it is recommended to get an annual screening done so that you eliminate the chances of finding it out late, and can check the growth of any anomalies as soon as they take place. Getting regular checks ups done and getting diagnosed for the problem when the earliest symptoms begin to show are both crucial for prostate cancer.


Prevention Of Prostate Cancer

Finding a lump on either breast is the biggest cause of concern for any woman. This is one of the most common characteristic signs of breast cancer. Making any woman stressed out on discovering a lump. Breast cancer is increasingly becoming a commonly found cancer but, not all lumps are cancerous. Lumps can appear on the breast tissue as a side effect of contraceptives or during menstruation. These lumps typically disappear on their own. When a lump on the breasts does not reduce but instead begins to grow larger, one must immediately consult a doctor.

Non-cancerous lumps on the breast are known as fibroadenoma. These are typically seen in women below the age of 30 years. Fibroadenoma can be described as firm lumps with well-defined contours. These may be very small in size and may move under the skin. However, they can be easily identified through a mammography or an ultrasound. Fibroadenoma rarely turns cancerous and can be treated without surgery with homeopathy.

Homeopathy is a holistic form of medication that does not treat only the symptoms exhibited but treats the root cause of the issue. It may be safely prescribed to women of all ages. A homeopathic remedy is dependent on the symptoms exhibited along with the patient s overall physical, mental, and emotional health. Thus, two women with similar lumps in their breasts may be prescribed different medication if one has a type-A personality while the other has a type-B personality. For this reason, it is important to remember that while homeopathy has negligible side effects, self-medicating might not have the best results. If you have noticed a lump on your breasts, you must consult a qualified homeopathic doctor to prescribe a remedy for you.

Homeopathic remedies not only reduce the lumps but will also keep them from recurring. These may be prescribed on their own or in a combination of two or more medicines. Homeopathy can be taken along with allopathic medicine as well. When taking these medicines, one must be careful of the dosage and the timing. Homeopathic medication must always be taken at least an hour before or after eating anything else. When it comes to homeopathy, progress may be slow. Hence, it is important to take the full course of medication and not change the dosage or medicine without the doctor s advice.


Breast Lumps - How Your Symptoms Define Your Line Of Treatment?

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!

Benign prostatic hyperplasia or BPH is a condition where the prostate gland gets enlarged. This is mostly common in men who are ageing. When the prostate gland gets enlarged, the flow of urine through the urethra gets blocked, and hence, several problems related to urination may occur. BPH occurs as a result of hormonal imbalance. If untreated, BPH can lead to severe bladder and urinary health conditions.
There are several symptoms and signs of benign prostatic hyperplasia. Here are 7 common symptoms:

1. A frequent need for urination: Men affected by BPH feel an increased need to urinate frequently. This gets enhanced during the night and is called nocturia. The patient may even need to urinate more than eight times a day. Due to the enlarged prostate gland, more pressure is put on the urethra, which leads to uncontrollable urination.
2. Urinating difficulties: The act of urination becomes difficult. Because of enhanced pressure on the urethra, the flow of urine to the penis from the bladder gets blocked. This makes a urine stream hard to start. The urine stream gets weak and interrupted, and more difficulty may be experienced during the end of urination.
3. Pain during urination and ejaculation: Due to pressure on the urinary tract and reproductive system, pain can accompany urination and ejaculation. Some patients tend to push urine out, which results in pain. The pain may also occur because of infection during BPH.
4. Blood in urine and an unusual color/smell: Urine may take a dark color and have an unusual smell due to urinary retention. Unpleasant urine smell signifies urinary tract infection. Blood in the urine may also result because of dilated veins present on the surface of the enlarged prostate.
5. Urinary retention: When a patient is unable to pass any urine, it is called urinary retention. Such a condition requires immediate treatment, and you need to consult a doctor immediately.
6. Urinary tract infections: Bacteria may start growing in the bladder when the bladder is not fully emptied of urine. This bacterial infection causes darkening of the urine, and emission of a foul odor.
7. Bladder stones: Bladder stones may develop because of the inability of the bladder to empty itself completely. This is a major symptom of BPH. Hard lumps of minerals or bladder stones are formed when the urine present in the bladder gets highly concentrated, which causes the crystallization of minerals. Bladder stones may cause infections, result in blood in urine, cause bladder irritation and may also block urine flow.

So you see that benign prostatic hyperplasia involves the enlargement of the prostate gland, and results in several problems related to urination and different symptoms. Hence, immediate treatment is advisable.

7 Symptoms of Benign Prostatic Hyperplasia

Medical science constantly challenges the boundaries by finding not only the cures to the most dangerous diseases, but finds a way to prevent them even before they occur. With years of research, practice and data available for analysis, scientists are using advanced technology in combination with years of research to create a predicting mechanism for often fatal diseases like cancer.

Breast cancer screening has always been done with mammography. The fact is that this method is only 75% accurate, laden with false positives and misses a whole set of women totally- and that too when cancer has already developed. Part of the problem comes from the dense breast tissue which one in three women have. This tissue masks the lumps, which makes it difficult for mammograms to accurately screen cancer.

Some breakthrough scientific methods are changing this by drawing on years of research to predict this deadly disease, years before it can manifest itself.

A genetic test to predict cancer 10-11 years ahead of time
This test was performed to see how environmental factors could influence cancer, along with habits like smoking, abusing alcohol or hormones, genetic changes that occur and are put a large percentage of the women at a high risk of developing this disease.

A simple blood test is used for the genetic analysis of hereditary cancer. Researchers found a biological marker, methylation of the ATM gene, which has a very high ability to predict the risk of developing cancer, several years before diagnosis. 'Methylation' concluded that when one biological indicator is exposed to carcinogenic substances, or other abusive substances like tobacco and alcohol, it may trigger the development of cancer. On the flip side, this test will take time to reach the commercial market and even then cannot give an exact timeline as to when someone may develop the disease.

A simple blood test to predict breast cancer 5 years before it develops
This is the kind of medical miracle the world is looking for. Last year in April, researches in Denmark identified a simple blood test that can predict breast cancer five years before it actually develops with an accuracy of a whopping 80%.

It works by "measuring all of the compounds in the blood to build a 'metabolic profile' of an individual, in order to detect changes in the way chemicals are processed, during a pre-cancerous stage," says Laura Donnelly, health editor at The Telegraph, which covered this development. Danish researchers observed 57,000 participants over 20 years, gathering blood samples along the way, specifically comparing a set of 800 women who remained healthy or developed breast cancer within 7 years of their first blood sample. The researchers found they were able to predict, with 80 percent accuracy, which patients would be affected by the disease, just by looking at the metabolic profiles they built from the participants' blood samples. The results have been published in Metabolomics.
