The short answer
Kate Jackson had her first mammogram in 1987, which found a small breast tumor treated with a lumpectomy and radiation. In 1989 a follow-up scan found residual cancer, and she had a mastectomy with reconstruction. She went public to encourage other women to get mammograms and is a long-time survivor and advocate.
Kate Jackson's first mammogram, in January 1987, found a small malignant breast tumor she could not feel.
She was treated with a lumpectomy followed by about five weeks of radiation, and returned to work quickly.
In September 1989 a follow-up mammogram found residual cancer in the same breast, and she had a mastectomy with reconstructive surgery.
She chose to make her diagnosis public specifically to encourage other women to get screened.

The full explanation.
Who she is
Kate Jackson is an American actor best known as one of the original stars of Charlie's Angels, where she played the practical, sharp-witted Sabrina Duncan, and later as the lead in the spy series Scarecrow and Mrs. King. Off screen, she became one of the more visible voices for breast cancer awareness in the late 1980s, choosing to speak plainly about a diagnosis that many public figures of the era kept private.
The diagnosis
In January 1987, while filming Scarecrow and Mrs. King, Jackson had her first mammogram. It found a small malignant tumor — one she had not felt and had no symptoms of. She told almost no one, checking into a hospital under an alias to have the growth removed and rearranging her filming schedule around the treatment.
Reflecting later on that moment, she said she had been forced to face her own mortality and to decide whether she wanted to live or die — and that choosing life changed everything. She was treated and given a clean bill of health.
That was not the end of it. In September 1989, a follow-up mammogram found cancer again in the same breast — cells that the earlier surgery had missed. "Evidently, they'd missed a little bit before," she explained.
The treatment
For the first cancer in 1987, Jackson had a lumpectomy, which removes the tumor while sparing most of the breast, followed by about five weeks of radiation therapy. She returned to her series roughly a week after surgery, working through the radiation treatments.
When cancer returned in 1989, she chose a more complete operation: a mastectomy along with reconstructive surgery. Her publicist described the prognosis as excellent. Rather than keep the news quiet, Jackson released a public statement, saying she was disclosing it to help other women facing the same situation and to encourage early detection through mammography.
What her story teaches
Jackson's experience is, above all, a case for screening. Both of her breast cancers were found by a mammogram, not by a lump she could feel — which is exactly what screening is designed to do: catch cancer before there are symptoms. Her very first mammogram found the first tumor, and it was a routine follow-up scan that caught the second.
Her two operations also illustrate the range of breast cancer treatment. A lumpectomy plus radiation is a breast-conserving approach, often used for smaller, early cancers. A mastectomy removes the breast entirely and may be chosen when cancer is more extensive or when it returns. Which path makes sense depends on the individual situation and is decided with a care team.
Her story carries a gentler lesson too: cancer can come back or be found again, and staying with a schedule of follow-up scans is how a recurrence gets caught early. It is also worth knowing the symptoms of breast cancer, even though — as Jackson's case shows — early cancers often have none at all.

The bottom line
Kate Jackson was diagnosed with breast cancer in 1987 and again in 1989, treated first with a lumpectomy and radiation and then with a mastectomy and reconstruction. She is a long-time survivor who used her fame to urge other women to get mammograms. Her story is a clear reminder that screening finds cancer before it is felt, that follow-up matters, and that speaking openly can help others act on their own health.

Common questions
▸What kind of cancer did Kate Jackson have?
She had breast cancer, diagnosed twice. Her first mammogram in January 1987 found a small malignant tumor, and a follow-up scan in September 1989 found residual cancer in the same breast.
▸How was Kate Jackson's breast cancer treated?
For the first diagnosis in 1987 she had a lumpectomy, which removes the tumor while sparing most of the breast, followed by about five weeks of radiation. When cancer was found again in 1989, she had a mastectomy along with reconstructive surgery.
▸Why did she need treatment twice?
A follow-up mammogram in 1989 revealed cancer cells remaining in the same breast that the earlier operation had missed. As Jackson described it, a little had been left behind, so she chose a mastectomy to remove the breast tissue more completely.
▸Why did Kate Jackson go public about her cancer?
She said she wanted to help other women facing the same situation and to encourage early detection of breast cancer through mammography. Her willingness to speak openly turned a private diagnosis into a public prompt for screening.
▸Is Kate Jackson still alive?
Yes. She is a long-time breast cancer survivor and has spoken over the years about the importance of early detection and not fearing mammograms.
