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

People suffering from sickle cell disease (scd) usually start showing symptoms very early. They can appear to show up even during the first year of life. Symptoms of a sickle cell vary from one person to another and can be mild to serious depending on the condition.

 

Sickle cell disease is a health condition that worsens with time. Despite the absence of any full-proof solution, some treatments prevent further complications. These treatments can help patients receive aid for a lifetime. Simply said, sickle cell diseases can be managed medically.

 ;

Treatment

Treatment in a sickle cell patient depends on the severity of the symptoms. Preventing complications and relieving pain is the primary aim of the diagnosis. They can range from medications to blood transfusions.

 

Concerns

Some of the concerns that need to be taken care of during the treatment of scd are-

 ;


	
	Prevent painful scenarios
	


A painful episode or sickle cell crisis can be avoided by consuming sufficient fluids, wearing warm clothing, and staying away from sudden temperature changes.

 


	
	Avoid infections
	


Children with sickle cell anemia are made safe from infections by using penicillin. Adults with anemia might need to take penicillin all their lives. Doctors should ensure that all vaccinations in children and adults are periodically done to avoid any infections. However, during the covid-19 pandemic sickle cell patients should take extra care.

 ;

Medications

While there can be numerous ways to manage sickle cell treatment, medications help in a significant way. Some of the prescribed medicines are-


	
	Hydroxyurea- it reduces the frequency of sickle crises. Pregnant women should stay away from this according to experts.
	
	
	Crizanlizumab- this drug injected into the patient can help reduce the sickle crises in adults and children over the age of 16.
	
	
	Voxelotor- it is an oral drug used in children over 12. It lowers the risk of anemia by improving blood flow.
	
	
	Pain-relievers- narcotics to prevent excessive pain can also be used during the treatment.
	


 

Surgical procedures


	
	Blood transfusion
	


It is used to prevent stroke and other related complications in patients. This can increase the number of red blood cells in the body that can help reduce the symptoms.

 ;


	
	Stem cell transplant
	


It is also called a bone marrow transplant and is used to replace affected bone marrow with a healthy one. This procedure is carried out between matched donor and recipient. Although it is a known cure for sickle cell disease, various risks involved make it a less used practice.

 

Can Sickle Cell Be Cured?

Atherosclerosis refers to a medical condition in which the arteries become hardened and narrowed due to the accumulation of cholesterol plaque in the walls of the artery, obstructing the flow of blood.

What are the causes?

Atherosclerosis is a slow but progressive disorder that starts with the damage of endothelium   cells lining the interior surface of lymphatic and blood vessels. This allows bad ldl cholesterol to build up in the artery walls. Over time, a plaque made of calcium, macrophages, and cholesterol grows to a certain size to clog up arteries, disrupting blood flow around the body.

Other factors leading to atherosclerosis to include  

High blood pressure

High levels of triglyceride in the blood

High cholesterol levels

Certain medical conditions   diabetes, obesity, insulin resistance

Smoking/use of tobacco

Inflammatory conditions like lupus and arthritis

Symptoms of atherosclerosis

Atherosclerosis may develop in childhood or during adolescence. Mild conditions may not reveal observable symptoms unless the arteries are clogged, and blood supply to the tissues and organs are restricted.

Signs of moderate to severe atherosclerosis depend on the affected arteries   it could be the arteries leading to your brain, your heart, legs and arms, or the kidney. The symptoms of atherosclerosis include  

Weakness and fatigue

Difficulty breathing/concentrating

Headaches

Facial numbness

Paralysis

Vomiting

Chest pain

Anxiety

Loss of appetite

Swelling in the feet and hands

If any of the above symptoms seem familiar to you, consult a doctor right away for treatment.

Can atherosclerosis be prevented?

The best way to avoid cholesterol plaque from building up in the artery walls is to prevent the onset of atherosclerosis with these preventive measures.

Eat healthy   avoid eating foods that are rich in saturated fats   red meat, butter and cheese. These increase your cholesterol levels drastically. Instead, include foods that contain unsaturated fats, like avocados, olive oil, fatty fish, nuts and seeds because these help to keep ldl or bad cholesterol levels down.

Stay active   exercising and staying active can help regulate your cholesterol levels and prevent certain conditions that might put you at risk for atherosclerosis.

Quit smoking   people who smoke should quit smoking because it is a major risk factor for atherosclerosis   it increases blood pressure, which in turn, affects your cholesterol levels.

Atherosclerosis can lead to complications. With precautionary measures and proper treatment, the condition can be avoided.

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.

Know How To Detect Kidney Cancer Early

The moment you are diagnosed with a tumour, the first thing your doctor will do is find out whether the tumour is benign or malignant   this will determine the course of your treatment. In simple words, benign means non-cancerous while malignant means cancerous.

Benign cancer

When tumour cells grow at a normal pace, it is known as benign or non-cancerous growth. In the case of benign cancer, the cells grow slowly and do not spread to other parts of the body or invade the adjacent tissues. Most often, these do not exhibit serious symptoms or pose a threat to your health. So, they are not a cause of concern. However, sometimes a benign tumour can press against nerves, tissues or the blood vessels, causing pain and discomfort.

Some common types of benign cancer are  


	
	Adenomas
	
	
	Fibromas or fibroids
	
	
	Hemangiomas
	
	
	Lipomas
	


Benign tumours, although tend to be harmless, may need to be operated. This is true for tumours that have grown to become large and weigh heavy. When these develop in the brain and cluster around to press against block channels or vital organs, the condition can be potentially dangerous. Moreover, certain types of non-cancerous tumours like intestinal polyps are precancerous   meaning they have the potential to turn cancerous. ;Surgery to remove this type of tumour can help prevent it from becoming malignant.

Malignant cancer

Malignant cancer refers to cancerous tumours that can potentially be fatal. Unlike benign cancer, malignant cancer progresses quickly and metastasizes to invade other organs, tissues or parts of the body.

Here are a few examples of tumours that are cancerous in nature  


	
	Carcinoma
	
	
	Sarcoma
	
	
	Germ cell tumour
	
	
	Blastoma
	


A tumour that has turned malignant, or has spread through the lymphatic system or bloodstream, may require aggressive treatment. Based on the stage of cancer, your ;oncologist will devise a treatment plan that might include immunotherapy, ;radiation therapy, chemotherapy ;or surgery.

Being diagnosed with a tumour can be hard to deal with. To find out if the tumour is benign or malignant, consult a specialist and discuss your concerns.
