In April, one day after undergoingemergency surgeryfor what was initially thought to be a spinal infection, the 51-year-old — newly released from prison — was preliminarily diagnosed with non-Hodgkin’s lymphoma, a cancer that develops in the lymphatic system.

“It was not an infection, it was a type of a non-Hodgkin’s lymphoma – it’s a type of a cancer,” said Dr. Hooman M. Melamed, an orthopedic spine surgeon at Cedar Sinai Marina Del Rey Hospital who has been treating the star. “We’re getting an oncologist involved and we have to figure out what the next steps are as far as chemotherapy or radiation or more spine surgery. Depending on the tumor type, depending on the sensitivity of the tumor – it just depends the type but I feel more than yes, she will undergo chemotherapy or radiation.”

The doctor added that it is a “preliminary diagnosis pending pathology and oncology results.”

Last week,a source told PEOPLEthat Miller was struggling amid her cancer diagnosis.

“She has two more chemo sessions to go, but she’s in a really bad place — mentally and emotionally,” said the source. “She’s really losing it.”
