What Is Cancer? Symptoms, Causes & Types

Introduction

Cancer is one of the most common health challenges affecting millions of people worldwide. Cancer is not a single disease, but a collection of conditions in which cells of the body grow uncontrollably and metastasize to other parts of the body. Knowing what cancer is, warning signs, causes, and the types of cancer can help with early detection and treatment.

This blog will explain the basics: cancer symptoms, causes of cancer, and the types of cancer, covering common questions that people often ask.

What Is Cancer?

Cancer starts when normal cells lose their ability to control growth and division. Instead of following the body’s signals to stop, abnormal cells multiply and form a lump or tumor. Some cancers form solid tumors, while other diseases of blood and bones, such as leukemia, do not form tumors.

Often when people search “what is cancer,” they want to know how cancer develops. Cells in our body grow, divide, and die in a controlled way. Cancer begins when there is a disruption in this cycle, and old or damaged cells do not die as they should, and new cells unnecessarily keep forming.

Common Cancer Symptoms

Identifying signs of cancer can be difficult because many signs and symptoms are similar to those of an everyday illness. But, some of them should make you take notice.
Some of the more common cancer signs and symptoms include:

• Feeling tired or weak all of the time
• Noticeable, rapid, unexpected weight loss
• Lumps or swelling that last and do not go away
• Cough or hoarseness that lasts a long time
• Repeated fevers or infections
• Changes in bowel or bladder habits
• Unusual bleeding or discharge.

Although the signs and symptoms mentioned above may not mean cancer, they may be early indicators of cancer. Paying attention to your body is the first step to getting diagnosed as early as possible.

Causes of Cancer: What We Know

Individuals often question, "what are the causes of cancer?" The fact is that there is no one underlying factor. Cancer is usually induced as a result of a combination of lifestyle, genetics, and environmental factors.
Common causes of cancer include:

• Genetics: Family history of certain cancers puts individuals at increased risk.
• Lifestyle habits: Tobacco, alcohol, and an unhealthy diet.
• Environmental exposure: Pollution, radiation, and chemicals.
• Infections: Certain viruses or bacteria can act as a catalyst for abnormal cell changes.

Researchers are continuing to study the association between causes and prevention of cancer, the bottom line is that avoiding known causes can significantly reduce risk.

Different Types of Cancer

When people ask the question, "how many types of cancer are there?" The answer is "more than 100." Each cancer type is named for the organ or type of cell in which it begins.
Some of the most prevalent cancer types are:

• Carcinomas: Cancers of the skin or internal organs (lung, breast, or colon, for example).
• Sarcomas: Cancers of connective tissue, such as bone and muscle.
• Leukemias: Cancers of the blood that begin in the bone marrow.
• Lymphomas: Cancers of the lymph nodes and immune system.
• Cancers of the brain and spinal cord: Cancers of the nervous system.

Knowing the various types of cancer can aid in helping a medical team determine a plan of treatment.

Cancer Types and Symptoms

Every type of cancer presents different challenges. For example:

• Lung cancer generally presents a persistent cough accompanied by difficulty in breathing.
• Breast cancer generally presents a lump that is painless, or discharge from the nipple.
• Colorectal cancer may present changes in bowel movement and/or rectal bleeding.
• Blood cancers may present fatigue, swollen lymph nodes, or repeated infections.

This shows how cancer types and symptoms vary greatly and why regular screening is important.

Cancer Symptoms and Treatment

Identifying problems early increases the ability to treat them. Doctors typically use multiple modalities to treat cancer, such as:

• Surgery: Remove the involved tumor.
• Chemotherapy: Medicines that kill cancer cells
• Radiation therapy: Targeted energy that destroys abnormal cells.
• Immunotherapy: Stimulation of the body's own defensive system.

Each treatment plan is individualized based on the stage of cancer, type of cancer, and overall patient health. Early detection of cancer symptoms and treatment planning can save lives.

Frequently asked questions (FAQ’s)

Q1: What is cancer in simple terms?
 A: Cancer is where cells of the body grow at an abnormal rate, form lumps or spread uncontrollably and compromise the function of the normal organ.

Q2: What are the early signs of cancer?
 A: Some common early warning signs include: weight loss, lumps, unusual bleeding, changes in the skin, or persistent fatigue. However, these will vary with each type of cancer.

Q3: What causes cancer?
 A: The causes of cancer involve a combination of genetics, lifestyle habits, environmental exposure (smoking) and to a lesser extent viral or bacterial infections.

Q4: How many types of cancer are there?
 A: There are over 100 different types of cancer, including lung, breast, colorectal, blood cancers, and neurological cancers.

Q5: Can cancer be prevented?
 A: Not all cancers can be prevented, but healthy lifestyle choices and routine check-ups decrease the risk for developing cancer, as well as avoiding tobacco products and early screening if symptoms arise.
