Breast cancer begins when cells in the breast start to get out of control. These cells are mostly in the form of a tumor that can be regularly seen on an x-ray or felt as a lump. The tumor is dangerous (malignant) if the cells attack the surrounding tissues or spread to far off zones in the body. Breast cancer happens mostly in women, yet men can get it, as well.

This is how breast cancer can spread:

Bosom cancer can spread through the lymph framework
The lymph framework includes lymph nodes, lymph vessels, and lymph liquid found all throughout the body
Lymph nodes are little, bean-shaped accumulations of immune system cells that are connected by lymph (or lymphatic) vessels. Lymph vessels resemble little veins, with the exception of that they transport a liquid called lymph (rather than blood) far from the breast
Lymph contains tissue liquid, waste items, and immune system cells. Breast cancer cells can enter lymph vessels and start to develop into lymph nodes
A large portion of the lymph vessels of the breast deplete into the:

Lymph nodes under the arm (axillary hubs)
Lymph nodes around the neck bone (supraclavicular and infraclavicular lymph hubs)
Lymph nodes inside the neck close to the breast bone (inner mammary lymph hubs)
Following are some of the causes of breast cancer:

Hormones play a part in creating breast cancer disease; however exactly how this happens is not completely known
Ordinary breast cells get to be distinctly carcinogenic in view of changes (transformations) in DNA
Yet, most DNA changes identified with breast cancer are gained in breast cells during a woman s life as opposed to having been acquired
Qualities that accelerate cell division are called oncogenes
Tumor silencer qualities are typical qualities that back off cell division, repair DNA oversights, or advise cells when to bite the dust
Certain acquired DNA transformations (changes) can drastically increase chances for building up specific growths and are in charge of a large number of tumors that keep running in few families
Some of the treatments of breast cancer include:

Health alterations: Body weight, physical action, and eating routine are all connected to breast tumor, so these may be territories where you can make a move.
Restorative alternatives for women at expanded hazard: For women who have certain hazard components for breast growth, for example, a family history; various restorative alternatives may counteract breast cancer.
Medications to lessen hazard: For women at expanded danger of breast cancer, medications, for example, tamoxifen and raloxifene, can reduce the hazard. However, these medications can have their own dangers and symptoms.
Preventive surgery: In case that you have a solid family history of breast cancer, you can talk with your specialist about hereditary testing. This test addresses changes in qualities that increase the danger of breast cancer; for example, the BRCA qualities. In case you have a hereditary change from a family with a transformation, however, have not been tried, you could consider surgery to bring down your danger of tumor.

Breast Cancer - Important Things You Must Be Aware Of!

If you are concerned about liver cancer, you should know that most people do not experience signs and symptoms of the cancer in the early stages. Liver cancer is a form of cancer which occurs in the cells of the liver. There are various types of cancer which can develop in the liver. Hepatocellular carcinoma (HCC) is the most common liver cancer which begins in the hepatocyte, which is the main liver cell.

Symptoms-

Usually there are no specific primary stage symptoms of liver cancer. Some symptoms which may develop include the following:

Unusual weight loss is observed

Loss of appetite and developing food aversion

Pain in the upper abdomen

Nausea followed by vomiting

General weakness with intense fatigue

Swelling in the abdomen

The skin may become yellow

White and chalky stools are likely

Causes-

In most cases, the causes of liver cancer cannot be clearly determined. In some cases, the cause is known, such as chronic infection with the hepatitis virus, which may lead to liver cancer. Liver cancer occurs when the liver cells undergo changes or mutations in their DNA structure. DNA mutations lead to changes in instructions of chemical processes taking place in the body. The cells may grow out of control and develop into a cancerous tumour.

Risk Factors-

There are several factors which enhance the risk of liver cancer. They are as follows:

Chronic infection with hepatitis B or hepatitis C increases the risk of liver cancer.

A progressive and irreversible condition known as cirrhosis leads to scar tissue formation in the liver, increasing the risk of liver cancer.

Certain inherited liver diseases such as Wilson s disease and hemochromatosis also increase the chances of liver cancer.

People with diabetes are also at a greater risk of having liver cancer.

Non-alcoholic fatty liver disease (NAFLD), which is the accumulation of fat in the liver, also increases the chances of getting this condition.

Excessive alcohol consumption is another factor which causes irreversible damage to the liver and the chances of getting liver cancer get boosted.

Exposure to aflatoxins, which are poisons produced by molds growing on poorly stored crops, make you more likely to get liver cancer.

Several tests and procedures are carried out for the diagnosis of liver cancer. These include blood tests for diagnosing liver function problems, and imaging tests such as ultrasound, CT scan and MRI scan.

Top 4 Symptoms Of Liver Cancer

Kidney Cancer, more commonly known as renal cancer, first presents itself in the lining of the kidney. It then grows malignant and forms a tumor. The good news is that renal cancer rarely spreads to other organs. The bad news is that the tumors grow quite large before they can be detected.

Causes-
Kidney cancer has been found to occur most often in people who are older than 40 years of age. Though the cause of the cancer is not definitively known, there are a few factors that might increase the risk of developing kidney cancer. These include-

1. Obesity- Obesity can cause hormonal changes which in turn can increase the risk of cancer.

2. Smoking- As with any other kind of cancer, nicotine consumption, in the form of smoking cigarettes, increases the risk of developing the disease. In the case of renal cancer, it can, in fact, double the chances.

3. Pain Medications- A prolonged use of pain relievers over a period of time can increase the risk of renal cancer. Certain components of the medication can lead to kidney damage.

4. Genetic history- A medical history of family members, especially siblings, with the disease can significantly increase the risk of kidney cancer.



Symptoms-
In its early stages, kidney cancer remains asymptomatic, but as the tumor grow in size, symptoms begin to present themselves. These symptoms might include the following-

1. Blood in the urine.

2. A gradual loss of appetite leading to weight loss.

3. A persistent pain in your abdomen in conjunction with a lump.

4. A fever that is neither a result of an infection nor a cold, and one that lasts for weeks.

5. Swelling of the legs and ankles.

Treatment
Treatment for kidney cancer will depend on the size and location of the tumour and whether it has spread to other organs or parts of the body. Therefore, to determine the stage of cancer, diagnostic tests such as biopsy, are performed along with urine and blood tests. After determination of your cancer stage, the doctor will perform either a radical or a partial nephrectomy, where the cancerous tumor is removed along with additional tissues. Often, kidney surgery is followed by kidney transplant if both the kidneys need to be removed in nephrectomy. However, if nephrectomy does not cure your kidney cancer, then your oncologist may recommend cryotherapy, radiofrequency ablation or arterial embolization.

Kidney cancer in its advanced stage is often treated with either biological therapy where your body s immune system is utilized to fight cancer cells or targeted therapy where drugs are used stop the multiplication of cancer cells by blocking their signals. Due to such advancement in cancer treatment, the rate of success has gone up in recent years but you also need to follow a healthy lifestyle to make sure that the treatment can bring out the desired positive outcomes.

Kidney Cancer - What Causes It?

Liver cancer is when the cells in the liver grow uncontrolled. As the liver filters blood from all parts of the body, one of the most common reasons for liver cancer is perhaps metastasis, which is spread from other parts. Through the blood, cancer cells from other parts reach the liver for filtration and can then make the organ cancerous.

In addition to this, there are other risk factors that can lead to liver cancer. For example, people suffering from obesity, alcohol and tobacco abuse, viral hepatitis (B or C), chronic liver disease (especially in men, who are more prone than women to develop cancer), cirrhosis and someone who has a history of a prolonged use of steroids can suffer from the disease. Also, while liver cancer is very rare in the Americas, it is very common in Africa and Southeast Asia as the prevalence of hepatitis is higher in these regions.

When it comes to the symptoms, it s acceptable that liver cancer is insidious, and the exact point of origin cannot be identified. It continues to grow until symptoms become evident, which are also nonspecific. Before analyzing your health on your own, it s always recommendable to seek an expert s final word on it. Let s take a look at the top signs that might point out towards liver cancer.

Abdominal pain: When you suffer a strong pain in the abdominal area, especially in the upper portion on the right side, it can signal a lump or a growing tumor in the liver. This can also be accompanied by middle or lower back pain.
Weight loss: Many a time, women who suffer from a sudden loss of weight can be going through a deadly disease like this one. In most cases, these weight loss cases show no attempts on the patient s side, that is, the weight loss occurred for unknown reasons. A loss of appetite, without any reasons, is another indicator. These can result due to unexplained reasons and should be taken seriously.
White, chalky stools:This one is another tell-tale sign of liver cancer. Often, people tend to ignore stools in light, flaky colors. It is always better to consult a doctor, as you might be ignoring a sign of potential cancer.
Bloating: When you feel certain heaviness or bloating in the upper part of the abdomen due to fluid accumulation it indicates, which is one of the indicators for testing liver cancer.
Frequent body conditions: Apart from the above mentioned symptoms, one can also consider personal health history when facing any liver-related problems. Recurring severe nausea and vomiting and general signs of lethargy and weakness can also indicate liver cancer. Also, personal health history with claims the patient suffered from jaundice (due to the accumulation of bile pigments in the sclera and skin) can also be taken into consideration.

Liver Cancer - 5 Common Signs Of It!

Brain mapping is a technique where the biological quantities of a human brain are represented as spatial quantities resulting in maps. As with many other medical technologies, brain mapping is fast-evolving as well. Among several uses, brain mapping is chiefly used while performing surgery on the brain.

When surgery is to be performed on the brain such as surgery for epilepsy, the surgeon would want to comprehend how the brain areas are affected by seizures. The surgical intervention is meant for removing as much as seizure focus as possible while preserving crucial functions like understanding, speech, vision, movement, and sensation.

Why is brain mapping performed?
Brain mapping is a process which helps in identification of functions of various parts of the brain. Mapping the brain by stimulating different areas of the brain areas can aid in creating a map for a particular person. The map allows the doctor in understanding what parts of the brain are responsible for performing critical functions including sensation, movement, speech and other functions.

Which functions of the brain can be mapped electrically?
Typical areas of the brain which have motor, language, visual and sensory functions are needed to be mapped. When current is applied to a single area at a time, the doctor understands which part of the brain is responsible for which function.
When the patient is not able to speak due to the current, then the area is likely to be crucial for language function. If the limbs, face or trunk of the patient stop moving as the current passes, the area that is tested is responsible for movement. On the other hand, if the individual experiences tingling, numbing, and other sensations when the current is applied, it means that a sensory region is discovered.

How is electrical brain mapping performed?
Electrical brain mapping for guiding brain surgery for epilepsy can be performed in two distinct processes: directly during the surgery or in a two-stage procedure.

Two-stage procedure:
In the first stage of the process, the surgeon creates an opening in the skull which helps in exposing the surface of the brain. Small electrical contacts or electrodes are placed on the brain surface even though no brain tissue is removed. As soon as the electrodes are in the right position, the scalp is closed. The electrodes not only record the seizure of the patient electrically but also allow mapping of various areas of the brain. The last stage is surgery where abnormal brain tissues are removed.

Brain mapping process during surgery:
Electrical brain mapping may also be performed during the surgery which exposes part of the brain. This is termed as intraoperative brain mapping since it occurs while performing the main operation. The process of mapping may last for an hour to several hours at a stretch.

Brain mapping is also used to diagnose neurodegenerative diseases like Alzheimer s and Parkinson s. In these cases, the brain map shows extreme shrinkage of the brain due to tissue loss.

Brain Mapping Surgery - Why It Is Performed?

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.
