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?

World hepatitis day is observed on july 28th every year to raise awareness about hepatitis disease among people. It is organized on the occasion of the birthday of Dr. Baruch blumberg who found the hepatitis b virus in the year 1967 and also developed a vaccine for it. Moreover, this day educates everyone about hepatitis infections, the efforts to fight viral hepatitis, and methods people can use for its prevention.

What is viral hepatitis?

Viral hepatitis or hepatitis disease is a condition of inflammation in the liver that leads to severe liver disease and hepatocellular cancer. With deaths happening every 30 secs from a hepatitis-related infection, it is important to treat viral hepatitis at the earliest. Hepatitis is of different types depending on the infection. 

 ;

Types

Viral hepatitis impacts millions worldwide, resulting in both acute and chronic diseases. There are five major classifications of viral hepatitis-

 


	
	Hepatitis a- it is a liver infection that can be prevented by a vaccine. It is a result of the infection as a result of the hepatitis a virus.
	
	
	Hepatitis b- it is an infection that happens due to the hepatitis b virus. It is spread through the blood or other bodily fluids of a person.
	
	
	Hepatitis c- it is a liver infection caused by the hepatitis c virus. It transmits through the blood of a person who is infected.
	
	
	Hepatitis d- delta hepatitis is another name for this virus and the hepatitis d virus is responsible for this. It happens to only those who are already hepatitis b infected. ;
	
	
	Hepatitis e- it is a liver infection resulting from a hepatitis e infection. It is usually found in a person s stool.
	


 

Symptoms

Hepatitis is a condition where you don t show symptoms till it is chronic and starts affecting your liver health. However, people in the initial stages of hepatitis infection might start reflecting symptoms. Some common symptoms of viral hepatitis are:

 ;


	
	Flu-like signs
	
	
	Darker urine color
	
	
	Fatigue
	
	
	Abdominal cramps and pain
	
	
	Appetite loss
	
	
	Weight loss
	
	
	Yellow skin
	
	
	Pale eyes
	


 

People at risk

The risk of catching a hepatitis infection is high in individuals working around these environments-

 ;


	
	Direct contact with hepatitis a infected person
	
	
	Male in sexual relation with another male
	
	
	Drugs abuser
	
	
	Ones with clotting factor disorder
	
	
	Who work with primates
	


 

World Hepatitis Day: Know All About The Disease

Blood is one of the most crucial elements of human existence. It works as a commute for oxygen and various nutrients in reaching the cells. These functions make blood a vital source for the body to operate. That said, india needs 38, 000 blood donations every day, which adds up to 5 crore units required in a year. However, only 2.5 crore units are available against the huge unfulfilled numbers. Hence, it is essential to recognize the importance of blood donation.

 

Why is blood donation important?

While blood donations are essential to help people with surgeries, they are equally vital during cancer treatments, chronic diseases, and gruesome injuries. Moreover, they also benefit the donors in a significant way.

 ;

Types of blood donations

Blood donations are of several types through which a single donor has the potential to help nearly three people.

 

Whole blood donation

It is the most common process of donating blood. One pint of blood collected supports numerous patients in the process. It is, then, divided into different components that aid the donation.

 ;

Plasma donation

The process of plasma collection is carried out through a method called apheresis. It divides plasma from other blood components. Its blood clotting abilities help trauma patients and people undergoing cancer treatment.

 

Platelet donation

The collection of platelets is also done using apheresis. Once identified in the donor s blood, the rbcs and the donor gets other fluids back. Cancer patients are the chief beneficiaries of platelets as they play a prominent role during cancer treatments.

 ;

Double red cell donation

Red blood cells are also collected through the apheresis process. It helps donors to donate twice the dose of a whole blood donation. One can help a patient suffering from blood loss using this method.

 

Advantages of blood donation

Blood donations have several advantages that people should know. They help fight many severe health conditions in the human body. Some of them include-


	
	Loss of blood due to internal or external injuries caused by accidents
	
	
	Sickle cell disease or other abnormalities that affect the blood
	
	
	In the treatment of cancer
	
	
	Cardiovascular or orthopedic surgeries
	
	
	Blood disorders
	
	
	Transplant processes
	
	
	Treatments involving plasma
	


 ;

Covid-19

According to food and drug administration (fda) reports, patients who have recovered from covid-19 can help others by donating blood plasma. They contain antibodies that fight the infection, helping their body fight the virus.

 

Benefits for the donor

Even the donors receive many health and social benefits because of blood donation. Where donated blood saves lives, experts suggest that donors can also benefit from the same. Some of these advantages include:

 ;


	
	Boosting cardiovascular health
	
	
	Maintaining blood pressure
	
	
	Contributing to the community
	
	
	Reducing the iron levels
	
	
	Improving overall health
	



 

Why Blood Donation Is Important?

As the name suggests, kidney cancer, also known as renal cancer, starts in the kidneys. It occurs when the healthy kidney cells grow out of control and become malignant to form cancerous tumours. ;Renal cell carcinoma is the most common type of cancer affecting the kidneys  here cancer begins in the lining of the tubes of your kidney.

Risk factors of kidney cancer

The exact cause of kidney cancer is not known. However, studies suggest that certain factors can make you susceptible to renal cancer. These include  


	
	Smoking
	
	
	Overuse of certain medications
	
	
	Excessive body weight
	
	
	Genes/heredity
	
	
	Gender   men rather than women are prone to kidney cancer
	
	
	An underlying health condition, such as ;high blood pressure
	


Early signs of kidney cancer

The symptoms of renal or kidney cancer depend on its types. In most cases, the disease does not exhibit noticeable symptoms in its early stages. This makes the diagnosis of cancer difficult. However, the signs become more apparent and observable as cancer starts to metastasize. You should watch out for these signs of kidney cancer -


	
	Bouts of blood in the urine   a condition commonly known as haematuria
	
	
	Pain on one side of the lower back (near the kidneys)
	
	
	A lump or mass on the lower back or side, where your kidneys are located
	
	
	Loss of appetite
	
	
	Tiredness or ;fatigue
	
	
	Unintentional weight loss
	
	
	Fever ;that does not cure in days
	
	
	Anaemia   low count of the red blood cells
	
	
	In men, a cluster of enlarged veins called varicocele may develop around the testicles (particularly around the right testicle), indicating the presence of a large tumour
	


Often, these symptoms are mistaken for those of other conditions or diseases. Therefore, it is important to consult a specialist.

If you encounter the above symptoms, or if you are concerned about any changes that you have been experiencing lately, talk to your healthcare provider. A doctor will enquire about the symptoms and might ask you questions related to these signs   how long have you been experiencing them, or how severe is the pain etc. This is crucial for early diagnosis and treatment of kidney cancer.

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.
 

What Are The Different Types Of Sickle Cell Disease?
