       Sept 1 (Reuters) - Oncology company Novocure  NVCR.O 
said on Tuesday a cybersecurity incident involving unauthorized
access to certain information systems in mid-August exposed
internal records of more than 1,400 U.S. patients.
    The breach adds to a growing number of cyberattacks on the
healthcare sector, including medical device makers Abbott
 ABT.N , Stryker  SYK.N  Medtronic  MDT.N  and Boston Scientific
 BSX.N , drugmaker Novo Nordisk  NOVOb.CO  and drug-delivery
equipment supplier West Pharmaceutical Services  WST.N .
    Here are some more details:
    * Novocure said it activated its cybersecurity response
plan, implemented containment measures and initiated an internal
investigation of the event.
    * The exposed data included internal company patient ID
numbers and general contact information for healthcare providers
the company works with and for Novocure employees such as their
job titles and phone numbers.
    * Data for fewer than 50 other patients in the western U.S.
that included additional identifying information was also
exposed.
    * The company said access to its medical treatment devices
was not obtained, and that all its systems are fully functional.
    * Novocure does not expect this cybersecurity incident to
have a material impact on its financials.
