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

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.

1. 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.

2. 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.

3. Avoid smoking and consume less alcohol: smoking is a very unhealthy and harmful habit. Smoking lowers the quality of your life, and causes numerous diseases. 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.

4. Practice breast feeding: breast feeding your children for a span of one year or more is likely to reduce the risk of breast cancer.

5. 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.

5 Easy Ways to Decrease Your Breast Cancer Risk

Noncancerous growths of the muscle tissue surrounding the uterus are known as uterine fibroids. This is a common disease which about 70 to 80% of women contract by the time they are 50 years of age. The uterine fibroids can sometimes be very big and cause heavy periods as well as severe abdominal pain while at other times, uterine fibroids give no signs or symptoms whatsoever and go away on their own. This is why it is crucial to know what type of uterine fibroids you have and how to diagnose them. Here are the types of uterine fibroids and how to diagnose them;

Types
There are three main types of uterine fibroids. They are;

1. Intramural fibroids
The most common type of uterine fibroids are intramural fibroids. They typically appear in the endometrium and may grow larger which results in your womb getting stretched.

2. Subserosal fibroids
Subserosal fibroids are called so because they form on the serosa. The serosa is the outside of your uterus. Sometimes, Subserosal fibroids may grow so large that your uterus appears bigger on one side.

3. Pedunculated fibroids
Pedunculated fibroids tumors are basically Subserosal fibroids with a stem. A base which supports the tumor is called the stem.

Diagnosis
There are a number of tests done to diagnose uterine fibroids. They are;

1. Pelvic exam
A pelvic exam is a thorough inspection of a woman&#x2019;s pelvic area. The organs which are in the pelvic area include the cervix, ovaries, uterus and vagina. Normally, this and the next test in this article are enough to diagnose uterine fibroids.

2. Medical history
The history of your periods as well as the other symptoms you have will often be enough to diagnose the uterine fibroids. If your medical history is not enough, then you might need to undergo a pelvic exam.

3. Pelvic ultrasound
An ultrasound is when high-intensity sound waves are used to produce images of the pelvic area. This is only done when a pelvic exam and your medical history are not enough to diagnose uterine fibroids.

Types and Diagnosis of Uterine Fibroids

Bone cancer is a cancerous tumour in the bone, destroying the normal bone tissues. Tumours on bone tissues are not always cancerous or malignant, they are mostly benign. Primary bone cancer is when the malignant tumour begins to form in the tissues of the bones, but when these cancerous cells spread to other body parts like breasts, prostate or lungs, it is called metastatic cancer. Primary bone cancer is less common than metastatic cancer.

Bone cancer can be of three different types:

Osteosarcoma: In this case, the malignant tumour arises from the osteoid bone tissue. This occurs mainly in the upper arm and knee areas.

Chondrosarcoma: In this case the cancerous cells form in the cartilaginous tissues, causing a lot of pain. This occurs mostly in the pelvic area.

The Ewing sarcoma generally arises in the bone but it can also form in the soft tissues. Other kinds of soft tissues affecting cancerous cells are known as soft tissue sarcomas.

Causes-

There aren t many clear defined causes; however, several factors have been identified by researchers.

Osteosarcoma is seen to occur more frequently in people who have been through a high external radiation therapy dose.

In people who have frequently been treated with anticancer medications, children tend to be most affected.

Heredity may be an adding cause, although the percentage of hereditary transfer of cancer cells is very low.



People with hereditary bone defects or implants have a higher chance of acquiring bone cancer.

Symptoms-

The most common and saddening symptom of bone cancer is painful, although not all bone cancers cause pain. Unusual or persistent swelling or pain around a bone maybe a red flag for bone cancer. In case of a situation like this, immediate doctor s opinion is required.

Diagnosis-

Usually, diagnosis of a bone cancer can be made using X-rays; for example, a bone scan, a computed tomography scan, a magnetic imaging procedure positron emission tomography, and an angiogram. Biopsy and blood tests are also helpful in bone cancer diagnosis.

Treatment-

The size, location and stage of cancer, age, and health of the person decide the kind of treatment that should be given to the patient. Various treatment options include chemotherapy, radiation therapy and cryosurgery.

Survival-

The combined survival rate of all sorts of bone cancers is 70%. This percentage may vary with the type of bone cancer and also its stage.

An Overview Of Bone Cancer

Even though brain aneurysms are becoming common these days, not all of them are required to be treated. In some cases, the physician may choose to observe an aneurysm closely before adopting any treatment measure. But in patients in whom an aneurysm has progressed to a severe level, there are two treatment options:

Open surgical clipping
Endovascular therapy or coiling
Open surgical clipping for brain aneurysms:
This procedure is typically performed by a neurosurgeon who makes an incision in the head. An opening in the bone is made, and then a clip is positioned by dissecting through the spaces of the brain. This aids in preventing the flow of blood into an aneurysm. In this procedure, the patient is required to stay in the hospital for two to three nights after which he or she is discharged.

Considerable modifications have been made in the open surgery techniques in the recent years. Neurosurgeons are now able to perform eye brow incisions or mini craniotomies for clipping an aneurysm. In these procedures, a small incision is cut out in the skin above the eyebrow for making a window. A tiny clip is placed across the mouth of an aneurysm to help it heal. But it is worthy of mention here that these are all invasive procedures and take relatively longer time to recover compared to the coiling process.

Endovascular coiling:

This treatment is also performed by a neurosurgeon, and it has been proved that this process is exceptionally suitable for patients with a ruptured aneurysm. Endovascular coiling is often done in coalesce with an angiogram, where a catheter is inserted into the vessel over the hip, which is then gradually carried to the vessels of the brain and finally to an aneurysm.
Then the coils are packed to the point where it rises from the blood vessel, which prevents the blood from flowing intothe blood vessel. Most patients undergoing this minimally invasive procedure can go home the day following the surgery. The success rate of this process is very high, and over 125,000 patients have been treated all across the globe with the help of detachable platinum coils.
Over the last few years, a substantial amount of advancements have taken place in the endovascular techniques. Recent developments show the use of flow diverting embolization devices, which are similar to a stent and are placed in the primary vessel, adjacent to an aneurysm. It diverts the flow away from an aneurysm and therefore, allows the neurosurgeons to treat the brain aneurysms, which were previously considered inaccessible and untreatable.
Both the procedures are quite efficient in treating a brain aneurysm. The most suitable option is dependent on a host of factors such as size, shape, location and overall health condition of the patient.

The uterus or womb, is a muscular structure and is held in place by ligaments and pelvic muscles. If these muscles or tendons become weak, they cause prolapse and are no longer able to hold the uterus in its place.

Uterine prolapse happens when the uterus falls or slips from its ordinary position and into the vagina or birth waterway. It could be complete prolapse or even incomplete at times. A fragmented prolapse happens when the uterus is just hanging into the vagina. A complete prolapse depicts a circumstance in which the uterus falls so far down that some tissue rests outside of the vagina. Likewise, as a lady ages and with a loss of the hormone estrogen, her uterus can drop into the vaginal canal. This condition is known as a prolapsed uterus.

Risks: The risks of this condition are many and have been enumerated as follows:

Complicated delivery during pregnancy
Weak pelvic muscle
Loss of tissue after menopause and loss of common estrogen
Expanded weight in the stomach area, for example, endless cough, constipation, pelvic tumors or accumulation of liquid in the guts
Being overweight
Obesity causing extra strain on the muscles
Real surgery in the pelvic zone
Smoking
Symptoms: Some of the most common symptoms of prolapse involve:

Feeling of sitting on a ball
Abnormal vaginal bleeding
Increase in discharge
Problems while performing sexual intercourse
Seeing the uterus coming out of the vagina
A pulling or full feeling in the pelvis
Constipation
Bladder infections
Nonsurgical medications include:

Losing weight and getting in shape to take stress off of pelvic structures
Maintaining a distance from truly difficult work
Doing Kegel workouts, which are pelvic floor practices that strengthen the vaginal muscles. This can be done at any time, even while sitting down at a desk.
Taking estrogen treatment especially during menopause
Wearing a pessary, which is a gadget embedded into the vagina that fits under the cervix and pushes up to settle the uterus and cervix
Indulging in normal physical activity
Some specialists use the following methods to diagnose the problem:

The specialist will examine you in standing position keeping in mind you are resting and request that you to cough or strain to build the weight in your abdomen.
Particular conditions, for example, ureteral block because of complete prolapse, may require an intravenous pyelogram (IVP) or renal sonography. Color is infused into your vein, and an X-ray is used to view the flow of color through your urinary bladder.
An ultrasound might be utilised to rule out any other existing pelvic issues. In this test, a wand is used on your stomach area or embedded into your vagina to create images of the internal organ with sound waves.
