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:

1. Smoking
2. Obesity
3. 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:

1. Blood in the urine
2. A lump on either side of the abdomen
3. Persistent pain on one side of the abdomen
4. Tiredness
5. Unexplained weight loss
6. 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.

Breast cancer is a type of cancer which occurs due to the development of cancerous cells in a person's breasts. Women are usually affected by breast cancer and breast cancer is one of the most common forms of cancer after skin cancer. Usually fatal if not diagnosed in its early stage, breast cancer is a very serious medical ailment. Read on more to find all about the different symptoms, causes, preventive measures and treatment of breast cancer.

Symptoms-

Breast cancer has a few distinct characteristics and if you have a few or all the following symptoms you could be more likely to suffer from breast cancer. 

1. The formation of a lump in your breast which is different from the surrounding tissue and usually more thickened.
2. The discharge of bloody fluid  material from the nipples.
3. Sudden change of the size, shape and appearance of the breast.
4. Certain distinct changes to the skin over the breast for example an indentation in the skin similar to that of a dimple.
5. Appearance of an extra nipple which is inverted.
6. If the darkened area around the nipples known as the areola is flaking or peeling off.

Causes-

Studies and researches remain inconclusive on what causes breast cancer. Breast cancer occurs due to abnormal division of the cells located in the breast which over time accumulate and form lumps. They
might spread to other parts of the body. Breast cancer is caused mainly due to a complex interaction of personal genetics, environment and lifestyle choices. Breast cancer can also be caused due to genetics as about 5% to 10% of cases are due to gene mutations which pass onto generations.

Risk factors-

There are certain factors which increase the probability of contracting breast cancer. Increasing age, personal and family history of breast cancer, obesity, radiation exposure, pregnancy at an older age, post-menopausal hormone therapy are some of the factors that increase the chances of breast cancer.

Treatment-

Several forms of surgical methods exist to treat breast cancer. Depending on the condition and spread of the disease a suitable surgery is performed. These include mastectomy, lumpectomy, axillary lymph node dissection and removal of both breasts. Other forms of treatment include chemotherapy or the use of high doses of drugs to destroy cancerous cells. Radiation therapy where X-rays are used to destroy the cancer cells is also effective. If you wish to discuss about any specific problem, you can consult a Gynaecologist.
