Pronunciation
The pronunciation of the term "IPA" is /aɪ piː eɪ/ in English.
Etymology

- Phonology: The study of the way sounds function within a particular language or languages. While phonetics concerns the physical production, acoustic transmission and perception of the sounds of speech, phonology describes the way sounds function within a particular language or languages.
- Transcription (linguistics): The systematic representation of spoken language in written form. The source of the words transcribe and transcription, the term means "to write across" in Latin, and it's the process of converting spoken language into written form.

polski), also known as a neoplasm, is an abnormal growth of cells that serves no purpose. The term tumour is not synonymous with cancer because tumours can be benign (not cancerous), pre-malignant (pre-cancerous), or malignant (cancerous).
Etymology
The word tumour comes from the Latin tumere meaning "to swell", which is a reference to one of the cardinal signs of inflammation.
Types of Tumours
Tumours can be classified as benign or malignant.
- Benign tumours are not cancerous and do not spread to other parts of the body. They can often be removed and, in most cases, they do not come back. Cells in benign tumours do not have the abnormal appearance that cancer cells do.
- Malignant tumours are cancerous. Cells in these tumours can invade nearby tissues and spread to other parts of the body. The spread of cancer from one part of the body to another is called metastasis.
Causes
The exact cause of a tumour is often unknown, but it is generally thought to be a result of a combination of genetic and environmental factors. Some known risk factors include exposure to certain chemicals and toxins, a poor diet, certain types of infections, and radiation exposure.
Diagnosis
Diagnosis of a tumour usually involves a combination of imaging studies, such as MRI or CT scan, and biopsy, where a sample of the tumour is examined under a microscope.
Treatment
Treatment options for tumours depend on the type of tumour, its location, and its stage. Treatment may include surgery, radiation therapy, chemotherapy, immunotherapy, targeted therapy, hormone therapy, stem cell transplant, or a combination of these.
