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

People suffering from lactose intolerance find it difficult to digest the lactose or sugar in milk, which results in gas, bloating or even diarrhea. An inadequacy of an enzyme called lactase, produced in the small intestine, is the root of lactose intolerance, a condition also known as lactose malabsorption.

How to deal with lactose intolerance in your child?

Cutting out on dairy products does not mean you would be deprived of sufficient amount of calcium. Find alternate sources of calcium in your food apart from dairy products, for instance, spinach, rhubarb, pinto beans oranges, milk substitutes such as rice milk or soy milk, canned salmon, juices, breads and broccoli.  Do give your child foods rich in vitamin D such as liver, eggs and yogurt. Asking your child to spend some time out in the sun can be a great idea in this regard, as well.  Your physician will prescribe you with calcium and vitamin D supplements.
Limit your child s intake of dairy products. Opt for small servings of milk so as to reduce the chances of gastrointestinal troubles. Your child should consume milk with other foods to delay the digestive process. Try out a variety of dairy products as not all of them possess the same amount of lactose. Buy lactose free products or use lactase enzyme drops or tablets that may aid your child in digesting different dairy products.
Probiotics are living organisms that exist in your intestine and help you in maintaining a healthy digestive system. Yoghurt and other supplement capsules are rich in probiotics. Hence, they can be perfect choices for your child. 

Lactose Intolerance -  How to Deal With It?

Tuberculosis is an airborne communicable disease that mainly affects the lungs. However, it can attack the other organs as well. A tuberculosis infection may be categorised as latent or clinically active. A person is said to be suffering from latent tuberculosis when he or she has been infected with the tuberculosis bacteria, but is protected from the germs by a strong immune system. People showing symptoms of the disease are said to be suffering from a clinically active form of tuberculosis and must seek medical attention as soon as possible.

The symptoms of tuberculosis may be hard to identify as they can be attributed to other causes as well. In some cases, the symptoms may not appear until the disease has reached an advanced stage. Some of the common symptoms associated with this disease are:

Weight loss
Fever
Dry cough
Excessive sweating at night
Unexplained tiredness
Poor appetite
Chest pain
People with a weakened immune system such as those suffering from HIV or those undergoing chemotherapy have a high risk of suffering from this condition. When the disease is in its active form, tuberculosis causing bacteria multiply rapidly and attack the lungs. From here they may spread to other parts of the body, such as the lymph nodes, kidneys, bones, spine, brain and skin. When it reaches an advanced stage, the symptoms vary according to the organ affected. For example, pain in the bones indicates that the bone tissues have been affected while coughing up blood is a sign of TB of the lungs.

Tuberculosis can be diagnosed through a blood test or with a skin test. An x-ray and a lab analysis of your sputum can also help differentiate between latent and clinically active forms of this disease.
In the case of latent infections, preventive therapy is prescribed to kill the germs before they become active. This typically takes the form of a single tablet that must be taken for six to nine months.

Clinically active tuberculosis can be easily treated and cured as long as the patient undergoes the complete course of treatment. Treatment for this disease usually takes the form of oral medication that must be taken for six to nine months continuously. This is because tuberculosis causing bacteria can take a very long time to die. In some cases, multiple drugs may be prescribed to reduce resistance to the drugs. When it comes to tuberculosis it is important to continue taking medication for its full course, even if the symptoms disappear and you are feeling better. 

7 Signs You Are Suffering From Tuberculosis!

One of the best and easiest ways to manage the symptoms of the chronic obstructive pulmonary disease or COPD is through a healthy and nutrient dense diet. This would not only help you to not only keep the severity of the symptoms in check but also to maintain a healthy weight.

Tips to keep in mind when choosing a diet

Managing Weight: It is essential for patients with COPD to manage their weight. The symptom of breathlessness could be more severe if you are overweight. You might feel fatigued and tired if you are underweight. Therefore it is crucial to monitor your calorie intake and therefore also your weight as recommended by the American Lung Association.
Balanced Diet: It is essential for patients with COPD to eat a healthy, nutritious and balanced diet. One that is varied and rich in fruits, vegetables, whole grains and lean meats or proteins according to a study published in the August 2014 issue of the International Journal of Chronic Obstructive Pulmonary Disease. A well-balanced diet will ensure that you get all the necessary vitamins such as C, E, and D that are necessary to help you cope with this condition.
Protein: Lean proteins such as eggs, meat, poultry, nuts, beans, and fish especially oily fish such as mackerel and sardines, should be incorporated into your meal plan. These proteins are necessary for patients with COPD especially if they are managing their condition through exercise.
Carbohydrates and food high in fibre such as lentils, oats, and beans will improve the functioning of the digestive system.
Potassium: Fruits and vegetables such as beets, potatoes, bananas are especially beneficial in preventing water retention in patients
Foods To Limit Or Avoid
People react differently to foods, there are some foods that patients with COPD should limit or avoid but if they do not seem to have an impact on your symptoms you can make them a part of your meal plan.

Limiting salt intake irrespective of whether you are a COPD patient or not is always a good step to take. But if you are a COPD patient excessive salt in your diet could cause fluid retention which could worsen your shortness of breath.
Dairy products such as milk and cheese can irritate the respiratory pathways making phlegm thicker.
Certain fruits and vegetables such as apples, cabbage, stone fruits such as peaches and soybeans can cause gas and bloating.
Caffeine in coffee and chocolate could interfere with certain medications that you have been prescribed. Confirm with your doctor if you can still include them in your diet. Patients with COPD need to drink plenty of fluids and it might be beneficial to opt for non-caffeinated beverages.
Fried, greasy and spicy food can cause gas and indigestion which can affect breathing.
Discuss your diet with your doctor or ask for a recommendation of a nutritionist who would help you to work out a meal or diet plan best suited for your condition.

Uterine fibroids, also known as leiomyomata, are non-cancerous growths which develop in and around the uterus or the womb and form benign tumors in course of time. Though there are several types of uterine fibroids, they are all consistently similar in their genetic makeup. They are generally classified depending on their specific locations:

Myometrial or intramural fibroids
Submucosal fibroids
Subserosal fibroids
Pedunculated fibroids
Signs and symptoms

In most cases, uterine fibroids display little or no symptoms at all. Therefore many women are caught unawares and do not realize whether they have leiomyomata or not. When symptoms do show, however, they may include any one of the following:

1. Prolonged menstrual periods, usually for seven days or even longer
2. Bloating belly or pelvis
3. Intensive bleeding during periods
4. Pain during sexual intercourse
5. Constipation

Treatment

Since uterine fibroids do not cause any significant complications, they normally do not require much treatment. The condition, however, can be treated through either one of the following approaches:

1. Non-surgical approach

(1) Alert and careful inspection as well as watchful anticipation of the growth and development of uterine fibroids
(2) Birth control pills or oral contraceptives which help reduce heavy periods caused by uterine fibroids
(3) Pain relievers to help numb the pain
(4) Intrauterine device along with levonorgestrel to help reduce heavy periods
(5) Iron tablets are helpful in substituting the blood loss caused by heavy menstruation

2.Surgical approach

i) Myomectomy

ii) Hysterectomy

These two procedures can be performed using several techniques like:

Laparoscopy
Open abdominal surgery
Robot-assisted laparoscopy
Vaginal approach
Hysteroscope approach
iii) Uterine artery embolization (UAE)

Lung diseases are some of the most common diseases suffered by human beings throughout the world. Smoking and infections are responsible for most lung diseases. The lungs perform one of the most important functions of the body. It is also one of the most active organs in the human body and hence lung problems can arise due to problems in any other part of the body. Some of the most common and infectious lung diseases are discussed below.

1. Asthma
Asthma is a common long term disease which is characterized by reversible airflow obstruction and bronchospasm. The symptoms of asthma include coughing, shortness of breath and tightness of chest. These symptoms may occur frequently during a day and depending on the person, it may become worse during night or during a certain exercise.

2. Pneumonia
Pneumonia is another common lung problem which is suffered due to inflammation in the microscopic air sacs in the lungs known as alveoli. Symptoms of pneumonia include dry cough, chest pain, breathing problem and fever. Pneumonia is caused most commonly by viruses or bacteria. It is also caused by certain medications and conditions which are popularly known as autoimmune diseases. There are a number of vaccines available to prevent certain types of pneumonia. Other methods include hand washing and refraining from smoking.

3. Tuberculosis
Tuberculosis is a very infectious disease which is caused by the bacteria mycobacterium tuberculosis. Although tuberculosis generally affects the lungs, but it has been known to affect other parts of the body as well. Symptoms of tuberculosis include cough containing sputum with blood, night sweats, fever and weight loss. Air is an active medium for spreading tuberculosis. This happens when people who already have tuberculosis sneeze, cough or speak. Infection occurs more in those who have hiv/aids or those who smoke. Prevention of tuberculosis includes staying away and keeping those who are at high risk, early detection and treatment and vaccination.

4. Mesothelioma
Mesothelioma is a type of cancer which affects the lungs. It affects the lining of the lungs and chest wall. Symptoms of mesothelioma include shortness of breath, swollen abdomen, cough, chest pain, weight loss and general lethargy. Mesothelioma is caused mainly due to exposure to asbestos. Those people who mine asbestos, produce products from asbestos, work with asbestos products are at high risk. Mesothelioma also results from genetical problems and due to infection caused by the simian virus 40.

5. Pulmonary embolism
This is a disease caused due to blockage of an artery in the lungs by a substance which has travelled from another part of the body by the bloodstream. Symptoms of this disease include chest pain, breath shortness and coughing up of blood. There may also be signs of blood clot in the legs.
