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

Liver transplantation or hepatic transplantation is the second most carried out transplant procedure in the world. It is a potentially difficult surgery that is performed by a team of two to four surgeons along with the help of anesthesiologists and nurses. It takes around 10 to 12 hours to complete the procedure as there are many anastomoses, sutures, reconnections, and disconnections, which are to be performed under the liver bed which is necessary for the transplant to be a success.

Tests required before a transplant is planned

Computed tomography, or CT scan which employs X-rays and a computer to create pictures of the liver, showing its size and shape. CTs and chest X-rays are also recorded to evaluate your heart and lungs.
Laser Doppler flowmetry: to check if the blood vessels to and from the liver are normal.
Echocardiogram to check the status of heart function.
Pulmonary function test or lung capacity test to study and determine the lungs' ability to exchange oxygen and carbon dioxide.
Blood tests are performed to determine the patient's blood type, clotting ability, and biochemical status of blood, and to determine liver function.
The liver transplant procedure

After an admission at the hospital, an Intravenous line is started in the patient's arm or hand. Other tubes (catheters) are put in their neck and wrist, or their collarbone or the area between the belly and the thigh (the groin). These are used to check heart and blood pressure, and to get blood samples.
The patient is placed on the back, over the operating table.
If there is too much hair at the surgical site, it may be shaved.
A catheter is placed into the bladder to drain urine.
After the patient is sedated, the anesthesiologist will insert a tube into the lungs. This is done so that the breathing can be helped with a ventilator. The anesthesiologist will keep checking the heart rate, blood pressure, breathing, and blood oxygen level during the surgery.
The skin at the surgical site will be cleaned with a sterile (antiseptic) solution.
The doctor will make a cut (incision) just under the ribs on both sides of the belly.
The doctor will carefully separate the diseased or the injured liver from the nearby organs and structures.
The attached arteries and veins are then clamped to stop the blood flow into the diseased liver.
The diseased liver will be cut off from the blood vessels and then removed.
The surgeon will check the donor liver before implanting it into the body.
The donor's liver is placed in the patient's body.
The incision will then be closed with sutures or surgical staples.

Liver Transplant Surgery - Understanding The Procedure!

Q1. What exactly is Laparoscopy?
Laparoscopy is an alternative to 'Open' surgery wherein the abdomen is opened by tiny 'key hole' incisions and surgery is done. 'Scopy' means the use of an endoscope or telescope to see inside the abdomen. This is attached to a camera and a light source and the inside of the abdomen is projected on to a monitor. The surgeon performs surgery looking at this screen. The surgeon makes a total of 2-4 small cuts on the abdomen ranging from half to 1 cm through which the telescope and other thin surgical instruments are passed into the abdomen. When the uterus is removed , known as hysterectomy, there is also a cut at the top of the vagina where the uterus is attached.
Q2. What kind of gynaecological surgeries can be performed by Laparoscopy?
Most surgeries done in gynaecology can now be performed by Laparoscopy and do not require the large incision as for open surgery. Laparoscopy can be done sometimes only for diagnosis and is called Diagnostic Laparoscopy, as in checking whether the tubes are open or not and to look for any causes of infertility or pain outside the uterus. In women who are unable to conceive, Diagnostic Laparoscopy is often combined with Hysteroscopy (endoscope inside the uterus, inserted from below, via the vagina). When laparoscopy is done to perform some surgical procedure inside the abdomen it is called Operative Laparoscopy. This may be for simple procedures like sterilization, minor adhesions, drilling ovaries; or for intermediate or major reasons like fibroids, endometriosis, removal of ovaries or tubes or both or removal of uterus, for staging of cancers or radical surgeries for cancer. However, about 5% of all surgeries including those for cancer or very large tumours may benefit from open surgery.
Q3. Why does an expert surgeon recommend Laparoscopy over Open Surgery?
Laparoscopic surgery has many advantages above open surgery: the incisions are much smaller (open surgery incisions are 8-10 cms long), therefore pain is much less; requirement for pain killers (which can have side-effects like sleepiness, impaired judgement) is lesser; hospital stay is shorter; complications fewer; requirement for blood transfusions infrequent; recovery in terms of physical, emotional and mental state is much better and quicker; return to work is faster with consequent lesser loss of working and earning days. Surgery with laparoscope is more precise because it is magnified view. Further vision is much better because it's like having your eye behind the structure because you can see with the telescope at places where the surgeon's eye cannot reach.
Q4. If the cuts on the abdomen are so small in Laparoscopic surgery, how do you remove the uterus or a large tumour from inside the abdomen?
Quite often if the tumour is not malignant and contains fluid, it is punctured to collapse it into a smaller size. If it is solid, it can be cut into smaller pieces inside the abdomen using a special instrument. The collapsed or cut structures can be removed gently through the 1 cm cut on the abdomen which may be increased a bit if required. After hysterectomy, the uterus can be removed easily from below, through the vagina.
Q5. Will there be much pain or discomfort after Laparoscopic Surgery?
There may be some pain and discomfort in lower abdomen for one day to few days after Laparoscopic surgery but this is much less as compared to open surgery because the incisions on the abdomen are much smaller and there is much less tissue handling inside the abdomen by fine instruments instead of rough, big, gloved hands which can cause tissue injury in open surgery. There may be some pain in the shoulder following laparoscopy. This is not serious and is due to the gas used in the surgery to make space for instruments.
Q6. When can I be discharged from hospital?
Following Diagnostic Laparoscopy or with simple Operative Laparoscopy you can expect to be discharged from hospital latest by the morning after surgery. In most other cases of intermediate or even major surgery, discharge is generally 1-2 days following the surgery unless there is some health issues prior to the surgery or any complication during the surgery. The complication rates for Laparoscopic surgery are not more than for open surgery and depend upon patient factors like anaemia, diabetes, obesity and skill of the surgeon.
Q7. When can I perform routine household activities or return to work after Laparoscopic Surgery?
Recovery after surgery depends upon many factors: presence of health problems before surgery; why the surgery is required; what surgery is being done; problems or complications of surgery, anaesthesia or blood transfusions. If all is well, one can perform routine household activities by 1 week, provided one doesn't feel tired. Although there may not be any harm, it may be unwise to be normally active within 48 hours of procedure. Following Diagnostic Laparoscopy or Operative Laparoscopy for simple procedures, one can return to work in 1 week. For other procedures, a 2-3 week off from work is reasonable. It depends on the type of work you are returning to. Avoid too rapid return to work if it is manually hard or requires standing for long durations of time. Sometimes a surgical procedure brings on a well needed rest and break from a lifetime of work. Mostly, when you return to work depends upon your own body and its signals of tiredness. You need to listen to those signals.


Know All About Gynae Laparoscopy Surgery

Of all cancer types that affect the female population, breast cancer is the most common one. Statistics show that above 1 in 8 women in the USA are likely to develop breast cancer (invasive type, which is often severe). Changing lifestyles including prolonged use of birth control, smoking, alcohol abuse, lack of physical activity, dietary changes, etc., have led to an increased incidence. As these are here to stay, the only way is to prevent.

The likelihood of developing breast cancer is determined by risk factors. Some of these risk factors cannot be changed. For instance, age, ethnicity, and history of familial breast cancer. However, there are others, which can be acted upon or modified to reduce the chances of developing breast cancer. 

Some of the preventable risk factors are as follows:

Nicotine abuse: Quitting smoking has multiple benefits for a woman, and one major benefit is the reduced risk of developing breast cancer. Other benefits include reduced incidence of diabetes, heart disease, and other cancers.
Hormone replacement therapy: To the extent possible, avoid prolonged use of birth control pills or hormones for other treatment purposes. In addition to using non-hormonal methods, if not avoidable, constantly monitoring hormone levels is very important. Birth control pills should especially be avoided by women over 35 years of age who smoke. The risk associated with developing cancer reduces as soon as the hormone supplement is stopped.
Weight Management: One of the major risk factors is obesity, and in people with other non-alterable risk factors, it is best to work on weight management from an early age. Talk to your doctor about your ideal BMI and ensure this is maintained.
Physical Activity: Regular physical activity, at least 30 minutes per day, in addition to strength training will help in keeping the body agile and managing weight. It also reduces the risk of breast cancer.
Breastfeeding: Studies have shown that breastfeeding has protective effect against breast cancer; longer a baby is breast fed, greater is the protective benefit.
Screening: Even if not completely preventable, early detection of breast cancer is very important. This will help in less severe treatment and better prognosis. Recommended ages for mammography are as follows: 
In the age of 40 to 44, an annual mammogram is advised along with a discussion with the doctor on the risks.
An annual mammogram for all women in the age of 45   54 is important as most women enter menopause by this time. This needs to be continued annually, as self-breast exams alone cannot detect cancer, thus it is a good practice and anything abnormal will not go undetected.
These will help reduce the risk of developing breast cancer, help in early detection, and improve prognosis.

Breast Cancer - 6 Ways You Can Reduce The Risk!

A fracture requires quick and careful medical attention to ensure proper healing and alignment of the bone. Most fractures usually recover within six weeks but that is only half the problem. A lot of other tissues get damaged in the process when there is enough stress placed in the body to fracture a bone. Additionally, when you are unable to move that bone, you will have joint stiffness and significant muscle weakness.

After a fracture, physiotherapy might be recommended to guarantee that you come back to your ideal capacity. You might have to go for regular appointments to your physiotherapist in order to achieve full recovery. Usually, your physiotherapist will try to prevent your post-fracture stiffness in the nearby joints and muscles after the initial six weeks while you are recovering from your fracture. After six weeks or later, if x-rays show that the bone has not been fully healed, your physiotherapist can take a shot at recovering full movement of the joints and muscles near the affected area. 

Here are five ways in which physiotherapy helps heal post-fracture:

Physiotherapy after a fracture can help you enhance your muscle movement. In case you have fractured your leg, your physiotherapist can help you improve your walk and help you decide whether you need to take the support of a walking stick, crutches or a cane. In case you have broken an arm or shoulder, exercises focused on reaching and grasping are included.
Modalities might be used to help with the pain and swelling. Your physiotherapist may choose to use ice, heat or whirlpool baths.
Electrical stimulation can also be used to improve your muscle movement. You need to keep in mind that while inactive treatments like electrical stimulation or ultrasound might be used, you also need to keep your muscles physically active to better your movement and strengthen your bones.
If you have had surgery to join the fractured bone, you may have surgical scar tissue. Scar massage can decrease scar attachments and increase movement around the scar.
Exercise to improve the scope of movement and strength can also be started. Particular focus points need to be treated in the joints around the fractured area. If you have fractured a bone close to your elbow, exercises need to be included for your elbow, wrist, and shoulder. Moreover, a fracture in the shin needs to include exercises for the knee, lower leg, and hip. Exercise can guarantee that your bone can endure the load during daily routine work. Make sure to consult with your physiotherapist to learn the correct exercises for your condition.
A fracture can be very painful and might lead to a disability or problem in movement. Depending on the seriousness of the damage, the loss may be temporary or permanent. Physiotherapy can help you come back to your optimum function as quickly as possible.

Physiotherapy - 5 Ways It Can Help Post Fracture!

The uterus is set up inside the pelvis with different muscles, tissue, and tendons. Due to pregnancy, labour or complicated delivery, in a few ladies, these muscles tend to weaken. Additionally, as a woman ages and with a loss of the hormone oestrogen, her uterus can drop into the vaginal canal, bringing about the condition known as a uterine prolapse.

The following conditions can bring about a prolapsed uterus:

Pregnancy with complicated or even ordinary delivery through the vagina.
Weakness in the pelvic muscles with the increase in age.
Weakening and loss of tissue after menopause and loss of normal oestrogen.
Conditions leading to increased weight in the abdomen, for example, constant coughing (with bronchitis and asthma), straining along with constipation, pelvic tumours (uncommon), or clogging of liquid in the abdomen.
Being overweight puts extra strain on pelvic muscles.
Previous surgery in the pelvic region leading to loss of outer support
Smoking
However, this condition can be treated effectively:

Self care at Home: You can strengthen your pelvic muscles by performing Kegel workouts. You do these by contracting your pelvic muscles, as though attempting to stop the stream of urine. This exercise makes the pelvic muscle strong and gives some support. Have your specialist train you on the best possible approaches to exercise your muscles.
Medications: Oestrogen (a hormone) cream or suppository ovules or rings embedded into the vagina help in strength and endurance building of the tissues in the vagina. However, oestrogen is just for use in some of the postmenopausal ladies.
Surgery: Based on your age and whether you wish to conceive a child naturally, surgery can repair the uterus or remove it. The uterus as in many cases can be expelled with a hysterectomy. During the surgery, the specialist can repair the hanging or saggy vaginal dividers, urethra, bladder, or rectum. The surgery might be performed by an open abdomen procedure, through the vagina, or through little cuts in the abdomen or vagina with particular instruments.
Other Therapy: In case that you do not need surgery or have a poor possibility for surgery, you may choose to wear a steady gadget, called a pessary. It is worn in the vaginal tract to strengthen the falling uterus. It can be utilised briefly or can be long-lasting. They come in different shapes and sizes and should be fitted according to the person. In case that the prolapse is extreme, a pessary may not work. Prolapse surgery is always preferred by vaginal route. Likewise, pessaries can disturb the insides of the vagina and may bring about a noxious release.
It can be prevented in the following manner:

Decrease your weight.
Try to avoid constipation by consuming a high-fiber diet.
Do Kegel exercises to strengthen the pelvic muscles.
Stay away from heavy lifting or straining.
