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

Cancer of the kidneys is amongst the ten most common types of Cancer. There are many types of renal cancer with Renal cell carcinoma being the most common amongst them. Renal cancer is said to be triggered by a genetic mutation but the cause for this mutation is yet unknown. While kidney cancer appears suddenly in some cases, in others it is inherited from the parents. Here are 4 things you should know about cancer of the kidneys.

Risk Factors
Along with a mutation of the genes which is beyond our control, some lifestyle factors can also increase a person s risk of suffering from renal cancer. Some of these factors are:

Smoking
Obesity
High blood pressure
Symptoms
An early diagnosis can make the treatment of renal cancer much easier than if it is left undiagnosed. Hence, it becomes important to recognise the symptoms of this disease. Common renal cancer symptoms include:

Blood in the urine
A lump on either side of the abdomen
Persistent pain on one side of the abdomen
Tiredness
Unexplained weight loss
Fever
These symptoms are common to a number of other diseases as well and hence if you experience them, it is best to get yourself checked out by a doctor. In order to confirm a diagnosis, your doctor is likely to ask for blood tests, urine tests, an ultrasound and a CT scan or an MRI. In most cases, your doctor will also schedule a biopsy to check for cancer cells in the kidney tissue.

Stages of kidney cancer
Once cancer has been diagnosed, your doctor will need to determine the extent of damage caused in order to find the best form of treatment for the disease. Stages of kidney cancer are determined by the size of the tumour and on how much it has spread from the original location. There are four stages of kidney cancer.
Stage I   When the cancer cells are restricted to the kidneys and the tumour is no bigger than 3  in diameter
Stage II   The tumour has grown bigger in size but is still restricted to the kidney
Stage III   The tumour may be big or small but has spread to at least one lymph node or has affected the blood vessels
Stage IV   The cancerous cells have spread to nearby lymph nodes or other organs or the tumour has grown through the fatty layer and outer fibrous layer of the kidney.

Treatment
Kidney cancer can be cured easily if detected in the early stages by removing the tumour and adjacent tissue or the entire kidney if need be. Removing one kidney is not fatal as a person can live a healthy life with a single kidney.

Kidney Cancer - How Its Stages Can Affect The Treatment?

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.

How Can You Prevent Breast Cancer?

Kidney cancer refers to any form of cancer that involves the kidney. The disease usually originates in two portions of the kidney   the renal pelvis and the renal tubule. It is one of the most common types of cancer, affecting nearly one out of every 63 people.

Obesity, older age, high blood pressure, smoking and others are some of the factors that increase the likelihood of developing kidney cancer. A person diagnosed with kidney cancer in the early stage will most likely encounter symptoms like   

  Blood in the urine 

  A lump near the kidneys 

  A persistent pain near the kidneys 

  Fever and night sweats 

  Fatigue and tiredness 

  Weight loss 

One should follow up with an oncologist upon experiencing the above symptoms. Is kidney cancer curable? Kidney cancer treatment depends on multiple factors   the stage and type of cancer, the patient s overall health condition etc. However, if cancer has metastasized, the doctor/specialist may recommend palliative treatment to manage the symptoms and improve your quality of life. 

Often, people think of palliative treatment as an end-stage treatment. Nevertheless, the approach can prove beneficial if given during the initial stages. It is about living for as long as possible in the most satisfying way possible. 

A team of healthcare professionals come together to meet your emotional, physical, and social needs. Treatment may include   

  Radiation therapy to ease pain from the disease that has spread to the bones

  Arterial embolization   a method that blocks the supply of blood to the kidneys and the tumour present inside 

  Immunotherapy   helps the immune system to fight against cancer cells 

  Targeted therapy   works by targeting cancer-specific proteins, genes and tissues that contribute to the growth of cancer 

Palliative treatment, as a part of integrated oncology, has been a boon to cancer patients worldwide. It not only helps deal with the disease physically but also helps to cope mentally. 

Kidney Cancer Cure - What Should You Know?

Uterine polyps are growths attached to the inner wall of the uterus that extend into the uterine cavity. Overgrowth of cells in the lining of the uterus (endometrium) leads to the formation of uterine polyps, also known as endometrial polyps. These polyps are usually noncancerous (benign), although some can be cancerous or can eventually turn into cancer (precancerous polyps).

Uterine polyps range in size from a few millimeters - no larger than a sesame seed - to several centimeters - golf-ball-size or larger. They attach to the uterine wall by a large base or a thin stalk.

You can have one or many uterine polyps. They usually stay contained within your uterus, but occasionally, they slip down through the opening of the uterus (cervix) into your vagina. Uterine polyps most commonly occur in women who are going through or have completed menopause, although younger women can get them, too.

Symptoms

Signs and symptoms of uterine polyps include:

Irregular menstrual bleeding - for example, having frequent, unpredictable periods of variable length and heaviness
Bleeding between menstrual periods
Excessively heavy menstrual periods
Vaginal bleeding after menopause
Infertility
Some women have only light bleeding or spotting; others are symptom-free.
When to see a doctor
Seek medical care if you have:

Vaginal bleeding after menopause
Bleeding between menstrual periods
Irregular menstrual bleeding
Causes

Hormonal factors appear to play a role. Uterine polyps are estrogen-sensitive, meaning they grow in response to circulating estrogen.

Risk factors

Risk factors for developing uterine polyps include:
Being perimenopausal or postmenopausal
Having high blood pressure (hypertension)
Being obese
Taking tamoxifen, a drug therapy for breast cancer
Complications

Uterine polyps might be associated with infertility. If you have uterine polyps and you're unable to have children, removal of the polyps might allow you to become pregnant, but the data are inconclusive.

Uterine Polyps - Symptoms, Causes & Complications Related To It! 

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.
