The surgery on her right breast and lymph nodes took place at Utah's Huntsman Cancer Institute and she's now recovering.
It was only last month that Chrissy was diagnosed with the rare form of breast cancer called Secretory Breast Carcinoma. A cancer so rare that no specialist across the country had ever seen it in a child so young, according to a GoFundMe page set up for the family.
Chrissy discovered the lump herself in October and told her parents, who quickly brought her to the doctor.
Both her parents have also been affected by cancer. Her mother once had cervical cancer and her dad is currently battling Non-Hodgkins Lymphoma.
But the family is staying positive. They also said that although the surgery is over, Chrissy still has a long way to go.
"We now have a 'new norm' which will take hold. She will be seeing her surgeon every 3 months to keep a very close eye on her as this type of cancer has a higher recurrence rate than others. And she'll have to undergo reconstructive surgeries throughout her young life to help with her development and her family will be here to love, encourage, and support her with every step!"
Secretory breast carcinoma is a slow growing breast cancer which is actually more common in younger patients, and was in fact originally termed ‘juvenile‘ breast cancer. It is called secretory carcinoma because of the abundant secretion of mucin within the tumor. It is one of the rarest types of breast carcinomas, accounting for less than 1% of all breast cancers. It can occur over virtually all age ranges, but the average age of presentation is estimated at around 25 years.
Secretory breast carcinoma is also a fairly benign type of breast cancer. It may be considered a subtype of infiltrating ductal carcinoma of the breast, but is generally associated with a better prognosis than generic ductal carcinoma. However, secretory breast carcinoma is prone to metastasis and local recurrence so must be treated aggressively.
