write a summary in one sentence from the paragraph “”” Low risk

Papillary or follicular thyroid cancer is put in the low-risk group when it:

    is only in the thyroid
    has not grown through the thyroid
    has not spread to nearby tissues or other parts of the body
    is 4 cm or smaller
    is not an aggressive variant, or subtype

When there is a very small amount of cancer (called micrometastasis) in 1–5 nearby lymph nodes, it is considered low-risk papillary or follicular thyroid cancer.
Intermediate risk

Papillary or follicular thyroid cancer is put in the intermediate-risk group when it:

    is an aggressive variant
    has grown through the thyroid and into tissues around the thyroid
    has spread to more than 5 lymph nodes in the neck
    has invaded blood vessels (called vascular invasion)

High risk

Papillary or follicular thyroid cancer is put in the high-risk group when:

    the cancer has spread to other parts of the body (called distant metastases)
    the cancer has grown through the thyroid and into many tissues in the neck (called gross extension)
    the cancer has spread to lymph nodes, and any lymph node with cancer in it is 3 cm or larger in diameter
    the cancerous tumour was not completely removed with surgery (called an incomplete resection)

Age is not a factor used in the ATA system, but differentiated thyroid cancer in people 40 years of age or older is considered a slightly higher risk.”””
