Does radioactive dating work for gases
Not everyone has radiotherapy as part of their treatment, but which one is used depends on the type of tumour and where it is in the body, among other things.
For example, a type of internal radiotherapy called radioactive iodine therapy is a very effective treatment for patients with thyroid cancer.
Over the years, scientists have come up with a number of ways to make radiotherapy more elegant and precise, but in principle the treatment remains the same: a high dose of radiation aimed at the tumour.
Although there are many types, broadly radiotherapy is given in 2 ways, from either outside the body (external radiotherapy) or inside (internal radiotherapy).
The radioactive iodine is given as a drink or in a pill and is then taken up by the thyroid cancer cells, but not healthy cells, and hence has few side effects.
This is known as radioactive liquid therapy and is one of two main types of internal radiotherapy.
Unable to cope with this assault to their lifeline, ultimately the cancer cells die.
Any harm to healthy tissues is a potential risk though and can lead to side effects.
Reducing this risk is crucial to making the treatment kinder for patients, and why modern radiotherapy techniques aim to minimise this collateral damage while also maximising the dose that the tumour gets.
Our scientists then continued to carry out pioneering research on radiotherapy, working out how to measure doses and showing how cells respond to radiation, among many other crucial studies.
Ultimately, this work laid the foundations for modern radiotherapy, which has dramatically improved since its inception.
