Understanding Cancer: A Complete Guide to Types, Symptoms, Diagnosis, Treatment, and Prevention

What is Cancer?

The Human body is made of tiny trillions of cells that divide via the cell cycle for their multiplication. When this process of cell division is disturbed by some factors, it starts to divide rapidly and abnormally. This disturbance in the process leads to the generation of tumors or cancer cells. Cancer is recognized as the abnormal and uncontrolled growth of cells in specific tissues or organs. Cancer can be of two types based on its character. Benign tumors are non-cancerous. It does not spread to nearby parts & grows slowly. Whereas, Malignant tumors spread to nearby tissues and can travel to distant organs in the body to form new tumors. This process is known as Metastasis.

Causes and Risk Factors

There are various causes and risk factors that can lead to cancer. It varies from person to person. It can be due to genetic, internal, or external changes. Some common risk factors for cancer are discussed below:

• Age: Cancer occurs at any age, depending on daily routine and lifestyle.

• Family history: People who have cancer in their bloodline and genetics are at higher risk of getting it.

• Infections: Having specific chronic infections also leads to cancer. Such as having chronic hepatitis raises the risk of getting liver cancer.

• Smoking and alcohol consumption: The risk of having cancer increases with smoking and alcohol consumption. Smoke alone elevates the risk of cancer for people who aren’t even smokers.

• Environmental factor: Environmental factors such as radiation, and exposure to certain carcinogenic chemicals damage the cell’s DNA and disturb the normal cell function. It leads to gene mutation and may raise the risk of getting cancer.

Types of Cancer

There are more than 200 types of cancer-based on which part of the body it occurs in. The names of these cells are typically derived from the organs from which they originate. Such as breast cancer occur in the breast, and ovarian cancer occurs in the ovary.
According to cell types, cancer is divided into five common types:

• Carcinomas: This kind of cancer spreads across the entire organ after starting in a primary cell or tissue. For instance, cancer that develops in a particular cell or organ, such as the prostate, colon, lung, or breast.

• Sarcomas: These are cancers that develop in the body's connective tissue and are challenging to cure. blood vessels, for example.

• Lymphomas and myelomas: Cancers that affect immune cells and reduce immunity include lymphomas and myelomas.

• Brain and spinal cord Cancers: Cancer begins in cells of the central nervous system and spreads to most parts of the brain.

• Leukemia: This type of cancer mostly affects the blood's white blood cells.

Cancer staging (0–4):

The stages of cancer are differentiated based on their growth and tumor size. They can be fast and slow-growing. It differentiates the seriousness of the tumor from least to highly aggressive. The size of the tumor and the extent of the spread areas describe cancer stages. As a result, there are five typical stages of cancer:

Stage 0

• Pre-cancerous stage
• Benign (Non-cancerous)
• Some abnormal cells under a microscope

Stage I

• Small tumor
• Very slow growth
• Long-term survival if treated
• Cured if removed by surgery
• The cell looks abnormal under the microscope.

Stage II

• Relatively slow growth
• Spreads to nearby healthy tissue
• Slightly abnormal in the microscope
• If not treated, it develops into high-grade tumors.

Stage III

• Malignant growth (Cancerous)
• Rapidly dividing cancer cells
• Spread fast to nearby lymph nodes

Stage IV

• Malignant tumor
• Most Aggressive
• spread in healthy body parts
• Abnormal and rapid cell division
• The tumor has a center of necrosis
• Can't be cured

Signs and Symptoms

The human body gives various signs that can be observed physically. However, it is very uncommon to have any symptoms at an early stage. Usually, screening tests and blood tests help to detect cancer at a very early stage. The signs of cancer become noticeable to the patient. Consult your healthcare expert if you observe any of these symptoms. Some common symptoms are mentioned below:

• High fever
• Severe headache
• Sudden weight loss
• Heavy sweating at night
• Unusual pain in the body
• Continue cough and hoarseness
• Unexplained bleeding and bruising
• Fatigue and tiredness without reason
• Unusual swelling and lumps in the body
• Disturbed bowel movement (Including constipation and Diarrhea)

Diagnosis and Testing

If you are seeing any of the symptoms mentioned, it is advised to consult a doctor. Various diagnosis methods for detecting cancer include:

• Clinical evaluation: The doctor will check the body for unusual pain or lumps. He may also ask for medical history, including alcohol consumption, past illness, and family cancer records.

• Imaging scans (CT, MRI, & PET): Some imaging tests are done to diagnose cancer. These tests help to visualize the affected area and tumor size and confirm the stage of cancer.

• Biopsy & lab tests: If the doctor suspects cancer, he will further go for a biopsy. In a biopsy, some sample tissues are removed using a needle from the target organ and examined under a microscope for detection of any cancerous growth.

• Genetic Testing: The doctor prescribes this testing if he suspects any genetic mutation. It detects the targeted gene that is responsible for cancer.

Treatment Options

There are various treatment options available for treating cancer. Doctors prescribe them after considering patients' reports, current body response, and medical history. Some of the treatment plans are discussed below:

• Surgery- Removing complete organs affected by cancer cells is done in surgery and is painful for patients. Surgery may lead to some mild to severe complications. Recovery might take weeks to months.

• Chemotherapy- This cancer treatment is one of the traditional and efficient approaches to treating cancer. In this process, heavy anti-cancer drug compositions are used to kill the cancer cells. Abra Bound 100mg Injection is a type of chemotherapy drug. You can buy it from Magicine Pharma. This is an online pharmacy that deals with all kinds of anticancer drugs. They offer great discount offers on anticancer medicines.

• Radiation therapy - In this therapy, high-energy radiation or X-rays are used to kill the cancer cells. It shrinks tumor cells before surgery and manages symptoms in the advanced cancer stage.

• Targeted therapy - It is a kind of cancer treatment that targets a specific gene or protein. This gene is responsible for the growth and proliferation of cancer cells.

• Immunotherapy - These medications are specific drugs that trigger the immune system to destroy cancerous cells. Some drugs, such as Avastin 400mg injection and Keytruda 100mg Injection are immunotherapy drugs. It is also available on Magicine Pharma at the lower price with original brands.

• Hormone therapy - This specific treatment is given in cancer that needs hormonal support to grow. Such as prostate and breast cancer. Fulvetraz 250mg Injection is a hormonal therapy injection for treating cancer.

Living with Cancer

Living with cancer is not limited to daily life changes, it is a long roller coaster journey to take off with it. It takes physical, mental, emotional, and even financial balance to keep on living. While cancer affects the daily routine, it is important to maintain a sense of living and heartfulness with a feeling of joy and life purpose. Taking support and talking with family, friends, healthcare professionals, or any loved one will help for sure. Remember that Cancer is not a reason to feel low; strategy can cope with it.

Prevention and Risk Reduction

To prevent and reduce the risk of having cancer, it is important to follow some instructions and make changes in daily life. These will maintain your body health along with minimizing the risk. Some of the preventive actions are listed below:

• Take a balanced diet
• Regular exercise and physical activity
• Avoid exposure to radiation or UV rays
• Avoid packaged food (Contains carcinogens)
• Limit the consumption of alcohol and smoking
• Seek genetic counseling if there is a history of cancer in your family.
• Get enough sleep to keep your body rested and reduce stress
