When abnormal cells grow inside the brain and are in the form of a mass the condition is called a brain tumour. There are various types of brain tumours that exist. Some of the brain tumours which exist are malignant or cancerous while other may be non-cancerous. A brain tumour can begin in any part of the brain and spread to other parts of the body or vice-versa. The growth rate of brain tumours is different for each individual suffering from it. As per studies, every 2 in 1, 00, 000 people are said to be affected by a brain tumour in india. However, it may come as a relief to some as not all brain tumours are cancerous or life-threatening. Some are benign tumours and seldom pose any threat to the affected individual.

 

Types of brain tumor

Brain tumours may be primary or secondary.

Primary brain tumour

In this type of brain tumour, the abnormal mass of cells that originated in the brain does not metastasize to the other organs. Based on their location in the brain, the primary brain tumours may be of the following types.


	
	Gliomas: one of the most common types of primary brain tumours, gliomas can have their origin in the spinal cord or the brain. Some of the common types of gliomas include astrocytomas (originates in the cerebrum of the brain), glioblastomas (these tumours form from the astrocytes which form the supportive tissues of the brain), ependymoma (these develop from the ependymal cells which are present within the cns), oligodendrogliomas (these tumours are found to arise from the oligodendrocytes).
	
	
	Schwannomas: also called acoustic neuromas, these primary brain tumours form on the nerves that play an important role in regulating the balance and hearing from the inner ear to the brain.
	
	
	Meningiomas: these types of tumours are usually benign and have their origin in the meninges (membranes surrounding the spinal cord and the brain).
	
	
	Primitive neuroectodermal tumours (pnets): primitive neuroectodermal tumours (pnets) are rare malignant tumours that originate from the fetal (embryonic) cells in the brain.
	
	
	Pituitary adenomas: as the name suggests, these tumours arise from the pituitary gland located at the base of the brain.
	
	
	Medulloblastomas: common among children, these malignant primary tumours develop in the brain (lower back) and gradually spread via the spinal fluid.
	


Other types of primary brain tumours include craniopharyngiomas and germ cell tumours.

Secondary brain tumours ;

Unlike the primary brain tumours, these tumours have their origin in the other body parts and organs (mostly in the lungs, skin, colon, breast, and kidney) and then gradually metastasize to the brain. Secondary brain tumours are found to be more common.

 

What Are The Different Types Of Brain Tumours?

Thyroid cancer refers to the type of ;cancer that originates in the thyroid gland. Cancer develops when the cells in your thyroid gland begin multiplying uncontrollably to form malignant tumours.

What leads to the development of cancer in the thyroid glands is not clearly known. However, a combination of environmental factors and genetics could be a leading cause of cancer.

Thyroid cancer is the sixth most common cancer in women, and usually affects those in their 20s and early 30s.

Types of thyroid cancer

Four types of thyroid cancer are prevalent, which are  


	
	Papillary thyroid cancer   ;this is the most common type of thyroid cancer. Cancer typically develops in one of the two lobes in the thyroid gland, and gradually spreads to the lymph nodes in your neck.
	
	
	Follicular thyroid cancer   ;the second most common type is the follicular thyroid cancer. Here the disease spreads to other body parts and organs, like the bones or lungs rather than the lymph nodes.
	
	
	Medullary cancer   cancer starts from the c-cells of the thyroid gland, which usually produce a hormone called ;calcitonin. The disease can spread to the lungs, liver, or lymph nodes even before a nodule is discovered.
	
	
	Anaplastic thyroid cancer   this form of cancer is rare but aggressive. It develops from an existing follicular or papillary cancer and spreads to other parts of the body faster than any other type of thyroid cancer.
	


Symptoms to watch out for

The symptoms of thyroid cancer depend on its type. Although there are no observable symptoms in the initial stage, you might be able to spot some changes in your body as cancer progresses. These symptoms include:


	
	A lump or mass in the neck that can be felt through the skin
	
	
	Change in voice   ;hoarseness
	
	
	Pain in the throat and neck
	
	
	Difficulty in swallowing
	
	
	Swelling of the lymph nodes in your neck
	


Diagnosis and treatment

The following tests/procedures can help detect thyroid cancer early  


	
	Blood test
	
	
	Ultrasound
	
	
	Biopsy
	
	
	Imaging tests
	
	
	Genetic testing
	
	
	Pet scan
	


Once cancer is diagnosed, appropriate treatment will be prescribed depending on the stage. Primary treatment options include  


	
	Chemotherapy ;  medications are infused through veins to kill cancer cells
	
	
	Radiation therapy   high-energy radio beams are directed to destroy cancer cells
	
	
	Radioactive ;iodine   large doses of radioactive iodine are given orally
	
	
	Targeted therapy   medications are given to attack certain vulnerabilities in the cancer cells
	
	
	Surgery ;  complete or partial removal of the thyroid gland or the lymph nodes
	


Prior to the treatment, your doctor will discuss the treatment plan specific to your diagnosis. Thyroid cancer is curable if detected at the right time. Therefore, do not lose hope and consult a specialist as early as possible.

Thyroid Cancer: Causes, Symptoms, And Treatment

Abstract

Background: it is essential to have an understanding of life expectancy and risk factors among patients with sickle cell disease (sickle cell anemia, hemoglobin diseases, and thalassemias). These are required to counsel the patients, target treatment, and plan the right clinical trials.

 

Methods: a research followed 3764 people ranging from birth to 66 years of age and suffering from scd. The procedure was done to understand the life expectancy and calculate the average age at death. Moreover, the study understood the reasons for the death in all 209 adults. It used the proportional-hazards regression analysis to know the risks for an untimely death in adults with sickle cell anemia.

 ;

Results: when the results for young kids and adults with sickle cell anemia were observed, it was found that the average age at death was 48 for women and 42 for men. Moreover, suffering from hemoglobin c disease had an average mortality age of 60 for men and 68 years for women.

 

In people with sickle cell disease, 18% of deaths took place in patients with mainly renal organ failures. 33% of the tested patients were medically free of organ failures but episodes of pain crisis took their life. Out of these patients, 78% experienced chronic pain, chest syndrome, or both, while 22% suffered a stroke that took their lives.

 ;

Clinical modeling showed that people with sickle cell anemia faced acute chest syndrome, seizures, kidney failure, a white-cell count of over 15, 000 per cubic mm, and a low hemoglobin level were related to a risk of early death.

 

Conclusions: results suggested that 50% of patients with sickle cell anemia lived beyond the age of 50. A huge share of those who lost their lives suffered no noticeable chronic organ failure. However, most of them died due to acute episodes of pain or stroke. Early death was seen highest among patients who had symptomatic disease. High levels of fetal hemoglobin suggested improved chances of survival and are assumably a credible source to foresee the risks and other factors related to adult life expectancy.

Life Expectancy And Risk Factors Involved In Sickle Cell Disease

Hepatitis is a condition that affects the liver by causing inflammation which is a common outcome resulting from a viral infection. While different types of hepatitis diseases are caused by different causes, there are some reasons like medications, toxins, alcohol, and drugs that are typically known.

 

Types

The five common types of viral hepatitis are hepatitis a, b, c, d, and e.

 ;


	
	Hepatitis a
	


Hepatitis a is the result of an infection caused by the hepatitis a virus. This type of hepatitis is an acute disease.

 


	
	Hepatitis b
	


The hepatitis b virus causes hepatitis b. This is often a chronic disease that lasts longer.

 ;


	
	Hepatitis c
	


Hepatitis c comes from the hepatitis c virus. It is one of the most common bloodborne infections in the world. It is a long-lasting condition.

 


	
	Hepatitis d
	


This is a not so commonly found form of hepatitis that only occurs in hepatitis b infected people. This virus not only causes liver inflammation but also cannot be contracted without an existing hbv infection.

 ;


	
	Hepatitis e
	


Hepatitis e is waterborne. Hepatitis e virus infection is responsible for it. It is generally acute but can be severely chronic for pregnant women.


 

Causes of viral hepatitis

It is true that different types of viral hepatitis infections are caused by distinct modes of transmission. Here are the causes of a hepatitis infection:

 ;


	
	Hepatitis a- when a person is exposed to the hepatitis a virus through food or water.
	


 


	
	Hepatitis b- when an individual comes in contact with hepatitis b virus through the transmission of bodily fluids like blood, semen, etc.
	


 ;


	
	Hepatitis c- when someone gets infected with the hepatitis c virus through the contamination of bodily fluids.
	


 


	
	Hepatitis d- when a person is exposed to hepatitis d virus-infected blood, it causes this disease.
	


 ;


	
	Hepatitis e- when a person comes in contact with the hepatitis e virus through water or food.
	


 

Causes of non-viral hepatitis

Although hepatitis is commonly caused due to an infection, other factors can also be reasons to cause hepatitis.

 ;

Alcohol

Excessive alcohol can lead to liver damage, causing inflammation. It can also be called alcoholic hepatitis. The alcohol impacts the liver cells directly. Moreover, it can also cause cirrhosis or even permanent liver failure.

 

Autoimmune system response

In rare cases, the immune system of a person attacks the liver itself. It leads to inflammation that can be mild to severe according to the infection. Moreover, it s more common in females than in males.

How Is Hepatitis Caused And Some Common Types?

All types of viral hepatitis diseases are contagious and they can be transmitted from one person to another easily. Although, the modes of transmission may vary.

 

Experts recommend some preventive steps for every type of infection to lower your risk of acquiring or spreading hepatitis infection.

 ;

Here are some preventive measures that may help in preventing the infection:

 

Vaccines

Vaccines for hepatitis a and hepatitis b are the best ways to prevent these viruses. Vaccines are not for all types of hepatitis infections. However, hepatitis a vaccination can help prevent the infection caused by the hepatitis a virus. The hepatitis a vaccine is generally administered in 2 doses. Similarly, there are vaccines available for hepatitis b as well. It is administered within 6 months duration. The same vaccine is helpful to prevent hepatitis d as well. There are no vaccines for hepatitis c and hepatitis e currently.

 ;

Reducing exposure

Hepatitis diseases can be transmitted through bodily fluids, water, and food containing the infection. One can lower the risk of contamination by minimizing contact with these agents. Practicing proper and good hygiene is a way to avoid getting hepatitis through these mediums.

 

You can decrease your risk of coming in touch with fluids containing these viruses by avoiding:

 ;


	
	Sharing used needles and razors
	
	
	Using someone else s toothbrush
	
	
	Touching spilled blood
	
	
	Not using condoms and dental dams during sexual contact
	


 

Handwashing

One must trust in personal hygiene to lower the risk of spreading or acquiring the hepatitis virus. Here are some preventive steps you can follow by washing hands:

 ;


	
	Washing your hands thoroughly after accessing the restroom
	
	
	When you get in touch with an infected person's blood, or stool
	
	
	After daycare routine for caretakers
	
	
	After a diaper change, and before serving food.
	


 

Avoiding contaminated consumption:

Contaminated or infected food and water may become the primary causes of hepatitis infection. One should take these precautions to avoid any contaminated consumption of food or water:

 ;


	
	Avoid eating raw shellfish
	
	
	Beware of fruits that have been washed in contaminated water
	
	
	Avoiding unhygienic street vendors
	
	
	Use bottled water for brushing or oral cleaning in areas where clean water is not available
	
	
	Bringing the water to a 1-minute boil is a must in doubtful areas
	
	
	Heated food to be eaten right away
	


Hepatitis: Some Ways To Prevent Yourself

What are the different types of sickle cell disease?

Sickle cell disease or sickle cell disorder is a term often used to talk about a group of diseases affecting hemoglobin. It is the oxygen-carrying element of blood that makes up 2 alpha globins and 2 beta globins. Sickle cell disease happens due to beta-globin mutation and depending on the abnormality in mutation.

Types-
Sickle cell diseases can be of many types depending on the gene mutation in the blood. Some of the common types are-

Sickle hemoglobin s disease (ss)
Hemoglobin ss disease or sickle cell anemia is the most popular type of scd. It takes place when hemoglobin s gene mutation is inherited from both mother and father. In simple words, it happens when the child inherits one substitution beta-globin gene from each parent. In this type, the body only produces hemoglobin s. It is mostly found in people of african and indian origin.

Sickle hemoglobin- c disease (sc):
Patients with sickle hemoglobin sc disease have a moderately dissimilar swapping in their genes of beta-globin. Here, both hemoglobin c and hemoglobin s are inherited from each parent. It may cause similar symptoms like anemia but remains relatively l. People of west african and mediterranean origin are more prone to this.

Hbs beta-thalassemia
People with this type of scd inherit one sickle cell gene s and one gene for beta-thalassemia from each parent. Zero and plus are the two common types of beta-thalassemia. While beta 0 thalassemia usually takes a severe form, beta + thalassemia is a milder form of the disease.

Sickle beta-zero thalassemia
Beta-zero thalassemia takes form when the child inherits the beta s gene from one parent and beta 0 thalassemia gene mutation from the other. With similar symptoms to anemia, it is a slightly severe form of beta-thalassemia.

Sickle beta-plus thalassemia
Substitutions in both beta-globin genes take place in patients with sickle beta thalassemia (sb) disease. This may even lead to the requirement of blood transfusion if no normal beta globin is produced. Mediterranean and caribbean people are more likely to have this disorder.

Hemoglobin sd, hemoglobin se, and hemoglobin so
These are the few rare and not less common types of sickle cell diseases. They are also less severe. People with these forms of scd inherit one sickle cell gene s and one gene from uncommon hemoglobin (d, e, or o) from each parent.

Sickle cell trait
Hbas
People with sct have one sickle cell gene s and one normal gene a from both mother and father. Ones with this disorder show few to no signs of the disease and usually spend a normal life. However, the risk to their future generations still exists.
