Samantha Harris may need to have chemotherapy after doctors discovered her cancer had spread.

The former 'Dancing with the Stars' co-host underwent a double mastectomy last month after being diagnosed with breast cancer, but medical professionals discovered the disease had spread further and they were forced to do some more testing.

Speaking to PEOPLE, she said: ''When I came to in recovery, my surgeon was standing over me with a look of sadness and told me that he had to take out all of my lymph nodes. A few days later I got some good news. Thankfully, only one node was positive. Unfortunately, that usually means chemo.''

The 40-year-old television personality admits she's ''scared'' about her possible treatment path, but insists she remains hopeful after meeting women who have been through it already.

She explained: ''I am scared by the prospect of chemo, but I know so many inspiring women who have gone through it and, as they told me, 'rocked it'. If I need it, I will take a deep breath and readjust my focus. Stay positive. When life deals you lemons, you gotta make lemonade!''

Samantha - who has daughters Josselyn, six, and Hilary, three, with her husband Michael Hess - first suspected there was something wrong when she felt a lump during a routine self-examination last year, and although nothing was detected during a prior mammogram, she still decided to see a specialist.

A needle biopsy followed by a lumpectomy found that she had breast cancer, and she previously admitted that at first she had no idea how she was going to cope.
