She is a mother of three on a mission. In the fight for her life, Jennifer Hayse is determined to beat the breast cancer that has dominated her life for two years.

"I really just haven't believed that I'm not going to beat it," said Hayse.

Local 4's Robin Simmons first met Hayse when she was pregnant with her third child and undergoing chemotherapy at the same time.

Hayse found the lumps herself. At 31 years old, a surgeon told her not to worry that they were most likely cysts.

"I think I was brushed off because I was only 31 and how could a 31-year-old have cancer in both breasts," said Hayse.

Doctors had told Hayse she should terminate her pregnancy, but the mother was eager to save herself and the baby girl she was carrying.

On Sept. 8, 2004, Angelina was born. She had two siblings, Nicholas and Natalie.

Weeks after Angelina was born, Hayse underwent a double mastectomy. Doctors could not remove all of the cancer. The tumor that was under her left arm was attached to the wall of a vein and wrapped around nerves, Local 4 reported.

In the one year since Hayse met with Local 4, she had undergone more chemotherapy and more radiation. She received the sad report that the treatment was failing and the disease was spreading.

"They know that the cancer is bigger instead of smaller, and they know that that's bad," said Hayse. "They know that I could die, and that's the worst of it."

Hayse hopes to find treatment somewhere beyond the United States.

She is on her way to Jerusalem, where she's discovered that they offer cancer treatments that the United States does not.

Hayse will travel 6,000 miles to the Hadassah University Hospital in Israel where she will undergo chemotherapy in high doses, bone marrow transplants and a procedure called donor lymphocyte infusion, an experimental treatment that has no guarantee.

"I won't be fighting just for me, I'll be fighting for other friends who have the disease and people I haven't even met yet who have the disease. I'll be fighting for them all," said Hayse.

The treatment and travel will cost up to $300,000, which is not covered by insurance.

Hayse's friends and former coworkers are organizing a fundraiser to help the the woman and her family pay for the treatment.
