Are you aware of the link between air pollution and cancer? Air pollution refers to the mixture of several harmful substances, which lead to various serious health hazards on exposure. The primary sources of air pollution are man-made, including fumes from automobiles and the smoke from burning fuels. Desert dust, radon gas, and several other natural sources of air pollution are equally dangerous. Air pollution is classified into outdoor and indoor air pollution. It is highly associated with increased risks of developing cancer. Smoking is considered to be one of the major agents, which pollute the air and increase the chances of cancer to a large extent.

Outdoor air pollution

Outdoor air pollution is strongly linked with cancer development.
As every person is exposed to some form of air pollution, it has a more harmful effect on the whole population across the globe as a general threat.
A certain part of outdoor air pollution referred to as PM 2.5, or solid dust particles, are highly responsible for the development of cancer.
The chances of cancer increase with the increase in PM 2.5 levels in the air.
Indoor air pollution

There are several sources of indoor air pollution that are closely associated with an increased risk of cancer.
The sources include fuels used for heating homes and for cooking, radon, and tobacco smoke.
Second hand smoke is another harmful indoor air pollutant that causes cancer.
Second hand smoke

Secondhand smoke increases the risk of cancer development, along with the risk of developing other diseases such as stroke and lung disease.
A lot of people all over the world get exposed to second hand smoke.
A lot of deaths occur due to cancer because of second hand smoke exposure which is common every year, all over the globe.
Radon

Radon is a natural radioactive gas, which is associated with increased risks of developing lung cancer.
It is found at low levels outdoors. It may also build in high concentrations indoors.
Although radon exposure does not pose a huge threat for cancer, a lot of radon-associated cancers develop due to exposure to radon, along with tobacco smoke.
Benzene

This is a flammable liquid having no color and with a sweet odor.
It is closely associated with the development of leukemia and cancers affecting other cells of the body.
Cigarette smoking and tobacco smoke are major cancer causing elements that are found in the air commonly. Both of these are quite harmful. It is recommended that you not only quit smoking, but also keep away from passive smoking.

Pollution and Cancer - How They Are Related?

Brain cancer is a disease of the brain in which cancer cells (malignant cells) arise in the brain tissue. Cancer cells grow to form a mass of cancer tissue (tumor) that interferes with brain functions such as muscle control, sensation, memory, and other normal body functions. Tumors composed of cancer cells are called malignant tumors, and those composed of mainly non-cancerous cells are called benign tumors. Cancer cells that develop from brain tissue are called primary brain tumors while tumors that spread from other body sites to the brain are termed metastatic or secondary brain tumors.

Prologue:

Brain cancer is actually the abnormal growth and uncontrolled growth of the cancer cells in the brain,that forms a tumor in the brain.Tumours can be either benign or malignant.

Benign brain tumours are abnormal collections of cells that reproduce slowly and usually remain separate from the surrounding normal brain.

Malignant tumours reproduce and grow quickly. Their borders are hard to distinguish from the normal brain around them.

Symptoms:

There are few early symptoms of brain cancer, but as the tumour grows within the confines of the skull, it causes increased intracranial pressure and exerts pressure on the brain, causing signs to develop.

Brain cancer symptoms and signs are varied and depend on the area of the brain involved, but can include:

Headaches.

Seizures.

Nausea and vomiting, which, CANSA reports, may be worse in the morning or after a sudden position change.

Difficulty walking or clumsiness.

Vision changes.

Changes in alertness.

Behavioural impairment.

Causes:

Brain cancer occurs when there is an uncontrolled growth of cancer cells in the brain that form a malignant brain tumor. The underlying cause of primary brain cancer, cancer that begins in the brain, is not known. Secondary brain cancer is caused by a cancer of another organ in the body, such as the breast, prostate, kidney, skin, or bone, that has spread to the brain.

What are the risk factors for brain cancer?

Certain inherited conditions, including neurofibromatosis, Von Hippel-Lindau syndrome, Li-Fraumeni syndrome, and Turcot syndrome

Personal history of cancer or family history of brain cancer

Impaired immune system

Radiation therapy of the head

Treatments Options:

Treatment

Surgery is the main form of treatment for brain tumors that lie within the membranes covering the brain or in parts of the brain that can be removed without damaging critical neurological functions. The goal is to remove the entire tumor, whenever possible, as a tumor may recur if any tumor cells are left behind. Radiation therapy and chemotherapy are generally used as secondary treatment for tumors that cannot be cured through surgery alone.

Stereotactic radiosurgery

Stereotactic radiosurgery is a treatment option that delivers a high concentration of radiation directly to the tumor in order to stop its growth, while delivering only a minimal dose of radiation to the surrounding tissue. Unlike conventional surgery, stereotactic radiosurgery does not require making an incision to remove the tumor. It can be especially effective in patients with many small metastatic brain tumors.

Brain Cancer

Science has advanced a lot through the ages. Doctors have also succeeded in curing many diseases in this time. But even with one of the most advanced technologies, they still haven t found a fool proof way to cure cancer. Even out of the many types of cancer, blood cancer is the worst among them. You surely wouldn t want to get into such a situation. Would you? The best way out of blood cancer is never to get one. To prevent it you can take care of a few things:

Maintaining proper body weight: Although you can t do much to prevent cancer, you must ensure that you maintain a healthy body weight. This implied that your BMI should be normal (healthy weight) so that you have a good chance of fighting it. It has been said by many leading institutions worldwide as the best way to prevent cancer. One can maintain proper body weight by making sure they exercise every day for at least 30 minutes and also maintain a well-balanced diet. This would help you maintain a healthy body weight.
Reduction in the consumption of calorie dense food: Not only because calorie dense foods like cold drinks increase your weight, the sugar mixes with your blood and thus is difficult to transport through the body. Thus they add a lot of impurities to the body and must be avoided for the best interests in your effort to fight cancer. The worst fact about calorie dense foods is that you can easily consume 1000   2000 calories long before you can satisfy your hunger. Thus, it also defeats your first preventive measure to avoid cancer.
Staying away from harmful chemicals like pesticides: You might not know it and be happily spraying pest control sprays everywhere without a proper mask thinking you will make the pests go away. What you don t know is that those pesticides are harmful for your blood and one should avoid them. To increase the probability of winning against blood cancer, it s vital to keep this in mind.
Consulting a doctor from time to time: One should always go and visit a medical practitioner from time to time so that they can maintain proper health. Furthermore, if you see symptoms like fever, frequent infections, night sweating, swollen liver with abdomen pain, enlarged lymph nodes (they are usually painless), then be sure to go to a medical practitioner. Always remember that prevention is better than cure. Thus one should try to prevent blood cancer not cure it.

Blood Cancer - How To Prevent It? 

Brain tumor refers to the development of unusual cells in the brain or around the nearby tissues and structures. Pediatric Brain Tumor means the development of these unusual cells in the brain of children. There are two types of brain tumors: Benign or non-cancerous and malignant or Cancerous. Tumors like ependymoma and medulloblastoma are quite common among children. The treatment of the tumor is determined by its severity, type, location, age, and overall health of the child. The treatment of Brain Tumor in children is different from the adult s treatment. One should ensure to consult with the pediatrician with the specialty in cancer and neurology. Brain Tumors in children are Primary Brain Tumors that develop in the brain or nearby tissues. This Primary Brain Tumor develops when the usual cells have DNA mutations or alterations. The alterations in the DNA permit the cells to develop and distribute or split with an increased rate and destroy the healthy cells. This leads to the development and collection of unusual cells forming a tumor. In most Primary Brain Tumor cases, the cause is not clear. Children with a family history of the genetic syndrome and Brain Tumor are more prone to the problem.

Symptoms-

The symptoms of the Pediatric Brain Tumor depend upon the severity, location, and type. There are a number of symptoms that are really common and are shared by other diseases. Other than this, there are symptoms which are possibly the signs of Brain Tumor among children. Adults and parents should consult a doctor if they find their children having the symptoms and signs for an unusual time.

Hearing issues

Frequent and severe headache

Fuller fontanel (soft spot) on the baby s skull

Vomiting or nausea

Behavior changes

Seizures

Sudden vision problems like double vision

Abnormal or strange eye movement

Increased heaviness or pressure in the head

Irritability

Slurred speech

Difficulty in swallowing

Weakness

Loss of appetite

Drooping on one side of the face

Difficulty feeding in babies

Loss of sensation on one side of the body

Imbalance or difficulty in balancing

Difficulty in walking

Diagnosis-

The diagnosis for the Pediatric Brain Tumor includes many lab tests. The doctor may initiate with some neurological examination like hearing, vision, reflexes, balance, and coordination. Any abnormality in these tests will lead to further examinations. There are some imaging tests that are used to determine the size and location of the tumor in the brain. These tests include MRI (Magnetic Resonance Imaging), PET (Positron Emission Tomography), and CT (Computerized Tomography). After the confirmation of the presence of a Brain Tumor, the specialist will further move to the Biopsy. It includes the removal of a sample tissue for analysis or testing. The type of biopsy that will be performed on the patient depends upon the location of the tumor. Other than the biopsy, the tumor tissue can be examined for molecular basis and genetic mutations. After that, Drug therapy can be designed according to the individual s requirements. It is important for the doctor and the patient to know if the tumor has been spread through cancer in other parts of the body. If it is true, then the doctor will perform more tests and examinations to know the root and initial location of cancer for further treatment.

Treatment-

The treatment of the Pediatric Brain Tumor is determined by the severity, location, size of the tumor, and age and health of the child. There is a number of treatments available with modern technology but their usage depends upon the patient s requirement.

Surgery that is used when the location of the tumor is approachable via surgery. When the brain tumor is small, it can be completely removed by the surgery. But when the tumor tissues are located nearby sensitive areas of the brain, then the surgery becomes risky and maximum tumor tissues are tried to be removed through surgery. The risk of the surgery depends upon the location of the tumor. An example can be vision loss if it is anywhere near the nerves connected to the eyes.

Targeted Drug Therapy helps to destroy the abnormalities of the cancer cells resulting in the destruction of the cancer cells.

Radiation therapy is used to kill the tumor cells by using high-energy beams. Radiation therapy can either be given by an external machine (external beam radiation) or in exceptional cases, radiation is positioned within the body (brachytherapy) near the tumor.

Chemotherapy includes the consumption of drugs to destroy the tumor cells. These drugs can be consumed in tablet form but for children, the drugs are mostly injected (intravenous chemotherapy).

Stereotactic Radio Surgery includes various radiation beams to perform extremely focused radiation therapy to destroy the tumor cells located in a small part.

Proton Beam Therapy carries higher targeted radiation doses to the tumor cells with minimum exposure of radiation to the healthy cells and tissues. It decreases the chance of development of fresh cancer cells.

Take Away-

Pediatric Brain Tumor is the development of unusual cells in the brain or around it. Although this is a life-threatening problem, however, with advanced technology, it can be treated successfully. There are no specific causes discovered by specialists but genetic mutations and family history cause it. The symptoms can be really common like headache and nausea but can also be specific like difficulty in coordination, reflexes, speech, and many more. The timely diagnosis and treatment can give a new life to the child and reduces the chance of development of fresh tumor cells in the future.

Pediatric Brain Tumor - Know In Detail About It!

A tumor is an uncontrolled and abnormal growth of cells. A brain tumor is thus an abnormal growth and multiplication of cells in the brain. The cell growth can also be in areas adjacent to the brain. The brain tumor may

Have its origin in the brain (Primary brain tumor), or
Its origin may be in some other parts or organs of the body, which gradually spreads to the brain (Secondary/metastatic brain tumor).
Not all brain tumors are harmful and life threatening.

Brain tumors that exist as noncancerous cell growths are known as Benign brain tumors. Benign brain tumors seldom pose any threat to life.

Brain tumors that are cancerous and, thus, harmful, are known as Malignant brain tumors.

Do not neglect any brain tumors (malignant or not). It is better to be safe than to be sorry.

Types of Primary brain tumors:

Based on its cell of origin, primary brain tumors (benign as well as malignant) may be of the following types:

Meningiomas: Brain tumors that originate from the meninges (the membranes that cover the brain and the spinal cord). Meningiomas are seldom malignant.
Acoustic Neuromas: A noncancerous cell growth that has its origin in the vestibulocochlear nerve (the eighth cranial nerve). This nerve connects the brain with the inner ear.
Gliomas: Here, the tumor has its origin in the brain and the spinal cord (glial cells). This type of brain tumors, in most cases (~80%), are malignant.
Primitive Neuroectodermal Tumors (PNETs): Extremely rare, PNETs are malignant tumors that develop in the embryonic cells in the brain.
Medulloblastomas: Medulloblastomas is a malignant brain tumor that mostly affects children. It originates in the cerebellum (lower part of the brain).
Craniopharyngiomas: A benign brain tumor that has its origin near the pituitary gland (base of the brain). Craniopharyngiomas are common in children.
Probability of a secondary brain tumor are more in people who have had;

Kidney cancer
Breast cancer
Lung cancer
Colon cancer
Melanoma
Symptoms:

The symptoms of brain tumor include:

Chronic and regular headaches.
A change in the headache pattern.
Seizures.
A person may experience vision problems (Peripheral vision may be affected, double or blurred vision).
There may be difficulty in hearing.
Nausea and vomiting.
Behavioral and speech problems.
An arm or a leg may lose sensation.
A person has difficulty with balance.
Diagnosis and Treatment:
Though brain tumor can affect anyone and everyone, its chances are higher in

People who are more exposed to ionizing radiation. People having undergone a radiation therapy are equally vulnerable.
Children as well as older people.
People having a family history of brain tumors.
The diagnosis includes;

An imaging test like the MRI, CT scan and PET (Positron Emission Tomography).
Biopsy, whereby samples of the abnormal tissue is collected and examined.
Neurological examination.
Treatment:

Surgery is an effective treatment for brain tumors.
One can also opt for:

Radiations, whereby the abnormal tumor cells are destroyed using protons and x-rays (high-energy beams).
Chemotherapy: In this treatment, the tumor cells are destroyed using strong drugs (taken orally or intravenously).
Radiosurgery.
Targeted drug therapy: This treatment blocks the abnormalities that are characteristically present only in the cancer cells.

Brain Tumors: Types, Symptoms, Diagnosis, and Treatment

There are two primary factors that are more likely to cause a stroke in a person i.e age and a family history. While both are inevitable, this necessarily doesn t have to be the fate of a person. Brain stroke is entirely preventable as with the case of other diseases. By working on the potential health risk factors, a stroke can be prevented. Here is a list of few such steps which, when followed can pay rich dividends to a person facing the risk of a brain stroke:

Blood Pressure: Blood pressure is the single most important factor that can increase the chance of a brain stroke. If a perfect blood pressure reading seems too difficult to achieve, a more realistic blood pressure target of 140/190 should be aimed for. Some of the common steps in order to achieve an acceptable blood pressure figure include reducing salt in the diet, exercising on a daily basis, regular intake of fresh fruits & vegetables and fast processed food containing processed fats. Finally, quitting drinking and smoking goes a long way in ensuring that a person is safe from strokes.

Losing Weight: Obesity increases the risk of diabetes and blood pressure subsequently increasing the risk of a stroke. Being overweight, therefore greatly increases the odds of a stroke. A BMI of 25 should be maintained by engaging in activities such as walking, running and playing on a daily basis.

Regular Exercise: Exercise is a clear mandate for people facing an increased risk of brain strokes. A moderate intensity exercise schedule for a minimum of 5 days per week is necessary. Some simple steps in order to achieve this include taking the stairs while climbing, joining a fitness club, 30 minutes of daily walk in a day etc.

Moderate Drink: Surprising as it may sound, moderate drinking on a daily basis can dramatically reduce the risk of a brain stroke. Red wine should be the choice of preference in this case. It should be ensured that the level of drinking does not surpass more than a glass. Regular drinking in excessive quantity can increase the chance of brain stroke.

Check For Atrial Fibrillation: This is a disease that is related to the heart due to an irregular heartbeat. There is a possibility of the clots travelling to the brain causing a brain stroke. Certain possible symptoms of this disease such as palpitation of heart and shortness of breath should be checked with a doctor to negate the chance of brain stroke. Certain blood thinners like warfarin and aspirin can shield against atrial fibrillation. A doctor has to be consulted before starting any medication related to the heart.
