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.

Lesser Known Facts About Blood Donation

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.
