Cancer: Types, Symptoms and Causes

Cancer: Causes, Symptoms and Types

Sadly, cancer remains a widespread and serious illness. It occurs when abnormal cells grow uncontrollably, and it stands as one of the leading causes of death across the globe.

Although it is a fatal disease, modern medicine has developed several treatments for its treatment, such as radiation therapy, hormone therapy, and chemotherapy.

However, if diagnosed with malignant cancer, the chances of survival are higher.

So, what causes cancer?

Studies show that most cases are due to common risk factors such as smoking, diet, alcohol consumption, and infections.

What are the main symptoms of cancer?

Symptoms vary depending on the type of cancer.

However, you should look out for the following general signs:

• Intestinal or bladder problems
• Fatigue or weakness
• Changes in skin appearance
• Prolonged coughing, shortness of breath
• Unexplained sweating and fever
• Changes in appetite
• Weakened immune system
• Unexplained weight loss or gain, etc.

If you notice any of these symptoms, consult a healthcare professional right away.

Five Most Fatal Types of Cancer

Lung Cancer

The lungs are vital organs of the respiratory system, essential for the exchange of oxygen and carbon dioxide.

It begins when abnormal cells grow in the organ and form malignant tumors.

Smoking is one of the most important factors that causes this disease. Carcinogens contained in cigarette smoke can damage DNA.

Just 10 to 15 percent of cases are found in individuals who have never smoked. Most of these cases are incurable, but treatment depends on the stage of the disease and the patient’s overall health.

However, some lung cancers can be controlled with anticancer drugs such as Gefitinib (Iressa) if the doctor deems it appropriate.

Breast Cancer

Breast cancer ranks among the most frequently diagnosed cancers in women.

Each year, over a million women receive a breast cancer diagnosis, according to survey data.

This form of cancer originates in the breast tissue and often presents as a noticeable lump.

There are many different types of this disease, but hormone receptor-positive breast cancer is one of the most common.

Risk factors associated with this disease include obesity, lack of exercise, and hormone replacement therapy.

Cervical Cancer

Thousands of new cases of cervical cancer are diagnosed in the United States each year. Cervical cancer develops when cells in the cervix begin to grow abnormally.

There are many risk factors that contribute to the development of this disease, including smoking, a weakened immune system, the use of oral contraceptives, and sexual activity during adolescence.

According to research, cervical cancer is the leading cause of cancer and the leading cause of death in women. In the early stages, there are no symptoms, but as the disease progresses, symptoms such as vaginal discharge and pain during intercourse appear.

Liver Cancer

Located on the right side of the abdomen, the liver plays a vital role in the digestive system. It performs a variety of functions, including producing bile to dissolve fat, releasing glucose as needed, and storing nutrients.

Liver cancer arises when a cancerous tumor forms within the liver tissue. The condition worsens due to abnormal proliferation of organ cells.

Colon Cancer

Colon cancer can cause changes in bowel habits, weight loss, and fatigue.

Most cases are caused by tumors in the wall of the colon, known as polyps.

So, it depends on the type of polyps. When the disease begins in a polyp, it grows along the lining of the colon or rectum.

It is important to raise awareness about the different types of cancer and ensure that people take warning signs seriously.

Also, for cancers such as colon, ovarian, cervical, rectal, kidney, and brain cancer, it is recommended to consider anti-cancer drugs such as Bevacizumab (Bevatas) and Everolimus (Evermil).
