No one knows why cancer happens in the thyroid. Some though as in Hurthle Cell Carcinoma are thought to be brought on by high levels of radiation, though that is not always the patients story.
Are you asking if a cancer is treated at the last minute? Often thyroid cancers are not found until either the patient notices either a swelling in their neck,(goitre) or they have trouble swallowing due to either the goitre or nodules pushing in the throat. There is no test available to screen for thyroid cancers. So the doctors will usually recommend surgery or medication as the way to deal with it. Most of the thyroid cancers are highly responsive to treatment.
As I understand, thyroid cancer is slow growing. Many times it is found on a routine well care physical like mine. It's important to do a neck check the best you can and help teach others how to do one to catch nodules as soon as possible while they are fairly small.
Don't get your Adam's apple confused with your thyroid gland. The Adam's Apple is at the front of your neck, the thyroid is further down, and closer to your collarbone
1. Hold the mirror so that you can see the area of your neck just below the Adam's apple and right above the collarbone. This is the general location of your thyroid gland.
2. Tip your head back, while keeping this view of your neck and thyroid area in your mirror.
3. Take a drink of water and swallow.
4. As you swallow, look at your neck. Watch carefully for any bulges, enlargement, protrusions, or unusual appearances in this area when you swallow.
5. Repeat this process several times.
The main reason of thyroid cancer is the low-dose radiation to the head and neck during infancy and childhood which is given for the treatment of many benign diseases. But later such patients are shown to have risk of thyroid cancer. The younger the patient was at time of exposure, the higher the risk of developing cancer. Another cause may be due to high-dose irradiation to the head and neck region. The following site has a lot of information about thyroid cancer-causes, symptoms and treatment.
