Difference Between Tumour and Cancer
Tumour and Cancer: What’s the Difference?
A tumour is an abnormal mass that may be benign or malignant; cancer refers to malignant disease and does not always form a solid tumour. Tumours are abnormal growths of cells and tissues, also known as neoplasms.
What are the Differences Between Tumour and Cancer?
The following table describes the major differences between a tumour and a cancer.
| Tumour | Cancer |
| A tumour is a swelling or mass of abnormal tissue or cells. | Cancer is a life-threatening disease where abnormal cells grow uncontrollably and invade or spread to other body parts. |
| It can become benign (non-cancerous) or malignant (cancerous). | Cancers are malignant tumours, as they can invade and spread to other organs. |
| Benign tumours do not metastasise but can sometimes cause symptoms or complications due to their size or location. They do not possess the ability to invade other tissues or organs. | Cancerous cells invade and disrupt the normal body functions, which can become fatal. |
| Cancer cells may acquire the ability to keep dividing; describing every cancer cell as immortal is an oversimplification. | Management of a benign tumour depends on its type, symptoms and location; some need observation while others need treatment. |
| Some benign tumours are asymptomatic, whereas others cause pain, pressure or organ dysfunction. | Cancer requires proper treatments, such as surgeries, chemotherapies and radiation therapies. |
What are the Types of Tumours?
A proper knowledge of the different types of tumours is important for accurate diagnosis and adequate treatment. Here are some of the common types of tumours:
Benign (Non-cancerous)
Benign or non-cancerous tumours do not invade nearby tissues or metastasise to other organs and remain asymptomatic within the body. These have fewer health complications and have a slower growth rate than malignant tumours.
Malignant (Cancerous)
Experts describe these tumours as cancerous, as they possess uncontrolled growth and invade other tissues. These tumours cause serious health risks and can interfere with the normal functioning of the tissues. Genetic and environmental factors are responsible for the occurrence of malignant tumours.
Precancerous
Precancerous changes are not always tumours; describe them as abnormal changes that may progress to cancer. They exhibit atypical cellular changes, which suggest a progression towards malignancy. Early detection and monitoring of precancerous tumours help prevent invasive cancer development.
What are the Different Types of Cancers?
Cancer has many unique characteristics depending on the category and individuals. Here we will discuss the types of cancers prevalent in the medical sector:
Sarcoma
Sarcomas are a special type of cancer that develops in connective tissues, such as muscles, fat, and bones. These are less prevalent than carcinomas. The most common types of sarcomas are liposarcoma(fat), osteosarcoma (bone), and leiomyosarcoma (smooth muscle).
Carcinoma
It is the most common type of cancer across the globe. It begins in the epithelial tissues that line body surfaces and organs. Subcategories of this cancer include squamous carcinoma (skin, lungs, and oesophagus), adenocarcinoma (glandular tissues), and basal carcinoma(skin).
Leukemia
This cancer develops in the blood-forming tissues, such as the lymphatic system and bone marrow. It shows characteristics of abnormal growth of white blood cells within these areas. The most common types include chronic lymphocytic leukaemia and chronic myeloid leukaemia.
Melanoma
Melanomas are a type of cancer that originates in melanocytes, which are the cells that produce melanin. These are highly prone to metastasis and can become aggressive if there is no early detection.
Understanding the proper types and categories of cancer and tumours can help doctors give proper treatment. Cancers are diseases that occur due to the uncontrolled growth and angiogenesis of abnormal cells. Indeed, not all tumours are cancerous, but some tumours can lead to cancer.
What are the Symptoms of a Tumour and Cancer?
Tumour symptoms depend on the size, where it develops, and whether it’s cancerous.
Sometimes, tumours may cause symptoms such as:
- Fever or chills.
- Feeling very tired
- Night sweats.
- Appetite Loss
- Unexplained weight loss.
- Painful lump
Symptoms of Cancer
- Fever or night sweats
- Persistent fatigue
- Changes in the skin
- Unexplained weight loss
- Persistent cough
- Trouble breathing
- Difficulty swallowing
- Hoarseness
- Mouth changes
- Bowel habit changes
However, these symptoms do not always indicate cancer. It is advisable to consult a healthcare provider for a proper diagnosis and treatment.
