Shannen Doherty has people ''lunge'' away from her because she has undergone radiotherapy.

The 45-year-old actress - who was first diagnosed with breast cancer in February 2015 and has almost finished chemotherapy but has recently started having radiation treatment - has admitted she was stunned when a person looked ''horrified'' and wanted to get as far away from her as possible when she spoke about her condition and the medical care she has received.

The former 'Charmed' star announced the news on social media, which saw her make fun of the heartless reaction.

Alongside a picture of her in the car with her husband Kurt Iswarienko - who tied the knot in 2011 - she wrote: ''Driving home from radiation with my love @kurtiswarienko Today, we were in an elevator and I was asked how I was feeling. I responded by saying that I had just gotten a radiation treatment so therefore very tired. The random girl on the elevator with us physically lunged away as far as she could. She then proceeded to look horrified for the next 3 floors. Just a heads up.... 1. You can't catch it 2. The radiation won't leak out of me and go into you. Hope that helps. #cancertruths from the #cancerslayer (sic).''

This must have come as a huge blow for Shannen as she has recently revealed she was frightened to undergo radiotherapy, and during her first session she was tempted to run away.

Speaking previously, she said: ''First day of radiation treatment. I look like I'm about to make a run for it which is accurate. Radiation is frightening to me. Something about not being able to see the laser, see the treatment and having this machine moving around you just scares me. I'm sure I'll get used to it but right now.... I hate it. #radiation #radiationmondaysucks #stillfightinglikeagirl (sic).''
